Highlights of GAO-09-685, a report to congressional requesters. 

Why GAO Did This Study:

Voting is fundamental to our democratic system, and federal law 
generally requires polling places to be accessible to all eligible 
voters, including those with disabilities. In response, states and 
localities have implemented provisions and practices addressing the 
accessibility of polling places. However, during the 2000 federal 
election, GAO found that only 16 percent of polling places had no 
potential impediments to access for people with disabilities. To 
address these and other issues, Congress enacted the Help America Vote 
Act of 2002, which required polling places to have at least one voting 
system accessible for people with disabilities. However, the extent to 
which state and local practices have improved accessibility is unknown. 

To respond to this issue, GAO determined (1) the proportion of polling 
places that have features in the path to the voting area that might 
facilitate or impede access to voting for people with disabilities and 
how these results compare to our findings from the 2000 federal 
election and (2) the proportion of polling places that have features in 
the voting area that might facilitate or impede private and independent 
voting for people with disabilities. To do this work, GAO visited 
randomly selected polling places across the country, which were 
representative of polling places nationwide, on Election Day 2008 to 
observe features and voting methods that could impede access and to 
conduct short interviews with polling place officials. GAO also 
reviewed relevant laws and documentation. 

What GAO Found:

We found that, compared to 2000, the proportion of polling places 
without potential impediments increased and the most significant 
reduction in potential impediments occurred at building entrances. We 
estimate that 27 percent of polling places had no features that might 
impede access to the voting area for people with disabilities—up from 
16 percent in 2000; 45 percent of the polling places had potential 
impediments but offered curbside voting; and the remaining 27 percent 
of polling places had potential impediments and did not offer curbside 
voting. While the percent of polling places with multiple impediments 
decreased significantly from 2000, still a fair number—16 percent—had 
four or more potential impediments in 2008. The most significant 
reduction since 2000 was that potential impediments at building 
entrances—such as narrow doorways—decreased from 59 percent to 25 
percent.

Most polling places we visited on Election Day 2008 had features in the 
voting area to facilitate private and independent voting, while some 
had features that could pose challenges. Virtually all polling places 
had at least one voting system—typically an accessible voting machine 
in a voting station—to facilitate private and independent voting for 
people with disabilities. However, we found that 29 percent of the 
voting stations were not arranged to accommodate a wheelchair. Seventy-
seven percent of polling places had voting stations with accessible 
machines that offered the same or more privacy than stations for other 
voters, while the remaining polling places had stations that offered 
less privacy. For example, some voting stations were not positioned to 
prevent others from seeing how voters using the accessible machines 
were marking their ballots.

The difference between the 2000 and 2008 estimates are statistically 
significant. For 0 impediments, the 95-percent confidence interval for 
2000 data is 11.3 to 21.6 and for 2008 data is 21.9 to 32.7. For 1 or 
more impediments, the 95-percent confidence interval for 2000 data is 
78.4 to 88.7 and for 2008 data is 67.3 to 78.1.

Congressional Requesters:

Voting is fundamental to our democratic system, and federal law 
generally requires federal election polling places to be accessible to 
all eligible voters, including voters with disabilities. In particular, 
the Voting Accessibility for the Elderly and Handicapped Act requires 
that, with a few exceptions, local election jurisdictions assure that 
polling places used in federal elections are accessible as determined 
by the state. These requirements can present a challenge to state and 
local election officials because achieving accessibility--which is 
affected by a person's type of impairment, as well as various barriers 
posed by polling place facilities and voting methods--is part of a 
larger set of challenges they face in administering elections on a 
periodic basis. Faced with these challenges, states and localities have 
implemented provisions and practices addressing the accessibility of 
polling places for people with disabilities. However, a 1999 study 
reported that people with disabilities were 10 percent less likely to 
be registered to vote, after adjusting for differences in demographic 
characteristics.[Footnote 1] Additionally, during the 2000 federal 
election, we found that only 16 percent of polling places had no 
potential impediments to voting access for people with disabilities-- 
although most polling places with potential impediments offered 
curbside voting.[Footnote 2] As the proportion of older Americans 
increases, the number of voters who may face challenges exercising 
their right to vote due to mobility and other impairments could grow.

Congress enacted the Help America Vote Act of 2002 (HAVA) to address 
these and other challenges raised during the 2000 federal election. 
HAVA required each polling place to have at least one voting system for 
use in federal elections that is accessible for people with 
disabilities by January 1, 2006. This voting system can be a direct 
recording electronic voting system (e.g., touch screen) or another 
system to provide people with disabilities the same opportunity for 
voting privately and independently as afforded to other voters. While 
our work since the passage of HAVA has reported improvements in state 
provisions and local practices to assure accessibility of polling 
places, the extent to which these provisions and practices have 
improved accessibility is unknown.[Footnote 3] To address this issue, 
you asked us to examine voting access for people with disabilities at 
polling places on Election Day--November 4, 2008. Specifically, this 
report examines (1) what proportion of polling places have features in 
the path to the voting area that might facilitate or impede access to 
voting for people with disabilities and how these results compare to 
our findings from the 2000 federal election and (2) what proportion of 
polling places have features in the voting area that might facilitate 
or impede private and independent voting for people with disabilities. 
[Footnote 4] This study is part of a broader GAO study, which we are 
also conducting at your request, designed to provide more detail about 
the proportion of polling places with features that might facilitate or 
impede voting for people with disabilities compared to 2000; describe 
state actions to facilitate voting access for people with disabilities; 
and identify the steps the Department of Justice has taken to enforce 
HAVA voting access provisions.

To do this work, we visited randomly selected polling places across the 
country on Election Day--November 4, 2008. We used a two-stage sampling 
method that created a nationally representative sample of polling 
places in the contiguous United States with the exception of those in 
Oregon.[Footnote 5] The first stage involved selecting a random sample 
of counties weighted by their total populations. We based the 
probability of each county's selection on the size of its population so 
that heavily populated counties, which tend to have more polling places 
than less-populated counties, would have a greater chance of being 
selected in the sample. This method allowed us to select a sample that 
was representative of polling places across the country on Election 
Day. In addition, the method we used allowed the possibility for 
counties to be selected multiple times, resulting in a final selection 
of 84 unique counties in 31 states (which was the equivalent of 100 
counties). The second stage involved randomly selecting eight polling 
places in each county for each time the county was selected. On 
Election Day 2008, we visited a total of 730 polling places.[Footnote 
6] At each polling place, we took measurements and made observations of 
facility features and voting methods that could potentially impede 
access--such as no accessible parking, high door thresholds, and ramps 
that were too steep or narrow. We also (1) identified features that 
could impede private and independent voting for people with 
disabilities in the voting area such as voting stations that were not 
properly configured for a wheelchair and (2) conducted short interviews 
with chief polling place officials to identify other accommodations for 
voters--such as curbside voting outside the polling place. We 
documented our observations and interviews with poll workers on our 
data collection instrument (DCI). The DCI was similar to the one used 
in our 2000 study of polling places, but we updated the DCI based on 
changes that have occurred in federal laws and guidance since 2000. 
[Footnote 7] We conducted our work from April 2008 through April 2009 
in accordance with generally accepted government auditing standards. 
Those standards require that we plan and perform the audit to obtain 
sufficient, appropriate evidence to provide a reasonable basis for our 
findings and conclusions based on our audit objectives. We believe that 
the evidence obtained provides a reasonable basis for our findings and 
conclusions based on our audit objectives.

This study focused on features in the path leading to and within the 
voting area that might facilitate or impede access to voting for people 
with disabilities. However, because the extent to which any given 
feature may affect access is dependent upon numerous factors--including 
the type or severity of an individual's disability--we were not able to 
determine whether any observed feature prevented access. Accordingly, 
we did not categorize polling places as "accessible" or "inaccessible." 
Moreover, we did not determine whether curbside or other accommodations 
offered at polling places actually facilitated voting. Finally, we did 
not assess polling places for legal compliance with HAVA accessible 
voting system requirements.

On May 15, 2009, we provided a briefing on the results of our work to 
your staff. With minor clarifications, this report formally conveys 
information provided during that briefing, which is reproduced in 
appendix I. We also provided additional information on our research 
methodology in appendixes II and III.

In summary, we found that compared to 2000, the proportion of polling 
places with no potential impediments increased and the most significant 
reduction in potential impediments occurred at building entrances. We 
estimate that 27 percent of polling places had no potential impediments 
to the voting area for people with disabilities--up from 16 percent in 
2000;[Footnote 8] 45 percent of polling places had potential 
impediments but offered curbside voting; and the remaining 27 percent 
of polling places had potential impediments and did not offer curbside 
voting.[Footnote 9] While the percent of polling places with multiple 
impediments decreased significantly from 2000, still a fair number--16 
percent--had four or more potential impediments in 2008.[Footnote 10] 
Over 50 percent of polling places had one or more potential impediments 
on the path from the parking lot to the building entrance, while 14 
percent had potential impediments from the building entrance to the 
voting area.[Footnote 11] The most significant reduction since 2000 was 
that potential impediments at building entrances--such as narrow 
doorways or high door thresholds--decreased from 59 percent to 25 
percent.[Footnote 12]

Most polling places we visited on Election Day 2008 had features in the 
voting area to facilitate private and independent voting, while some 
had features that could pose challenges. Virtually all polling places 
we visited had at least one voting system--typically an accessible 
machine in a voting station--to facilitate private and independent 
voting for people with disabilities. However, we found that 29 percent 
of the voting stations were not arranged to accommodate a voter in a 
wheelchair.[Footnote 13] Seventy-seven percent of polling places had 
voting stations with accessible machines that offered the same or more 
privacy than stations for other voters, while the remaining polling 
places had voting stations that offered less privacy.[Footnote 14] For 
example, some voting stations were not positioned to prevent others 
from seeing how voters using the accessible machine were marking their 
ballot.

We provided officials at the Department of Justice and the Election 
Assistance Commission an opportunity to provide technical comments on a 
draft of this report. The Department of Justice provided a technical 
comment, which we incorporated into our report.

We are sending copies of this report to the Department of Justice, the 
Election Assistance Commission, the U.S. Access Board, relevant 
congressional committees, and other interested parties. In addition,

Appendix I: Briefing for Congressional Requesters on Preliminary 
Findings: 

Voters with Disabilities: More Polling Places Had No Potential 
Impediments Than in 2000, but Challenges Remain: 

Briefing for Congressional Requesters on Preliminary Findings: 

May 15, 2009: 

Overview: 
* Introduction; 
* Research Objectives; 
* Summary of Findings; 
* Background; 
* Scope and Methodology; 
* Findings; 
* Next Steps; 
Appendix I. 

Introduction: 

During the 2000 federal election, a GAO study[A] found that only 16 
percent of polling places had no potential impediments to voting access 
for people with disabilities, although most polling places with 
potential impediments offered curbside voting. 

While the Help America Vote Act of 2002 (HAVA) is designed, in part, to 
address these issues, questions remain about whether people with 
disabilities encounter more challenges voting at polling places than 
those without disabilities. 

This briefing is part of a broader study to provide more detail on 
whether voting access at polling places has improved since 2000, 
identify state practices to facilitate access, and describe the 
Department of Justice’s (Justice) role in enforcing voting access under 
HAVA.

Alternative Voting Methods, GAO-02-107, (Washington, D.C.: Oct. 15, 
2001). 

[End of section] 

Research Objectives: 

1) Determine the proportion of polling places that have features in the 
path to the voting area that might facilitate or impede access to 
voting for people with disabilities and determine how these results 
compare to our findings from the 2000 federal election. 

2) Determine the proportion of polling places that have features in the 
voting area that might facilitate or impede private and independent 
voting for people with disabilities. 

[End of section] 

Summary of Findings: 

Compared to 2000, the proportion of polling places without potential 
impediments increased—from 16 percent to 27 percent in 2008. 

Virtually all polling places had voting systems to facilitate private 
and independent voting, although some had features that could pose 
challenges. 

[End of section] 

Background: 

Limited Federal Role in Election Administration: 

Federal elections are generally administered under state laws and 
policies, and primary responsibility for managing, planning, and 
conducting elections typically resides at the local jurisdiction level. 

Prior to 2002, several federal laws applied to voting, and some 
provisions specifically addressed accessibility issues for people with 
disabilities. These include: 

* The Voting Rights Act of 1965; 

* The Voting Accessibility for the Elderly and Handicapped Act; 

* The Americans with Disabilities Act of 1990. 

The Help America Vote Act of 2002 (HAVA) Added New Requirements for 
Voting Access: 

HAVA requires each polling place to have at least one voting system for 
use in federal elections that is accessible for voters with 
disabilities, which can be a direct recording electronic (DRE) voting 
system or other system equipped for people with disabilities. 

HAVA also requires that the accessible voting system should provide the 
same opportunity for people with disabilities to vote privately and 
independently as afforded by voting systems available to other voters. 

HAVA required states to comply with these requirements by January 1, 
2006. 

Department of Justice Oversees Compliance with Voting Access 
Requirements of HAVA and ADA: 

Justice enforces compliance with the voting access requirements of HAVA 
by pursuing litigation, on a case-by-case basis. Additionally, Justice 
oversees other voting legislation. 

Justice issued the Americans with Disabilities Act: ADA Checklist for 
Polling Places in February 2004 to help local voting officials 
determine if polling places have basic accessibility features for 
people with disabilities. 

[Note: We will address the role of Justice in overseeing HAVA voting 
access compliance and enforcement in our broader voting access report 
that we plan to issue in September 2009.] 

[End of section] 

Scope and Methodology: 

Updated Data Collection Instrument Used During 2000 Federal Election: 

* Reviewed relevant legislation, guidance, and other documentation. 

* Interviewed officials at Justice and the Election Assistance 
Commission. 

* Received input from the U.S. Access Board, disability advocacy 
groups, and national associations representing election officials. 

* Pre-tested our data collection instrument (DCI) during the 
presidential primary election in South Dakota in June 2008 and during 
the congressional primary election in Wisconsin in September 2008.

Objective One: Compared to 2000, More Polling Places Had No Potential 
Impediments and the Most Significant Reduction Occurred at Building 
Entrances: 

Overview of Finding 1: 

* The proportion of polling places without potential impediments in the 
path to the voting area increased since 2000. 

* The proportion of polling places with potential impediments that did 
not offer curbside voting remained about the same. 

* Polling places that had four or more potential impediments decreased. 

* Potential impediments at building entrances dropped sharply.

Source: GAO analysis of polling place data collected on November 7, 
2000 and November 4, 2008. 

The difference between the 2000 and 2008 estimates are statistically 
significant. For 0 impediments, the 95-percent confidence interval for 
2000 data is 11.3 to 21.6 and for 2008 data is 21.9 to 32.7. For 1 or 
more impediments, the 95-percent confidence interval for 2000 data is 
78.4 to 88.7 and for 2008 data is 67.3 to 78.1.

curbside voting: 28%. 

2008: 
Polling places with no potential impediments: 27%; 
Polling places with one or more potential impediments that do offer 
curbside voting: 45%; 
Polling places with one or more potential impediments that do not offer 
curbside voting: 27%.

data is not significant. The 2008 data is subject to sampling error of 
plus or minus 8 percentage points at the 95-percent confidence level. 
The 2008 pie chart only adds up to 99 percent because we rounded each 
percentage point to the nearest whole percent.

Objective Two: 

Most Polling Places Had Features in the Voting Area to Facilitate 
Private and Independent Voting, While Some Had Features That Could Pose 
Challenges: 

Overview of Finding 2: 

* Almost all polling places had at least one voting system to 
facilitate private and independent voting for people with disabilities. 

* Some voting systems had features that could pose challenges for 
voters in wheelchairs. 

* Most polling places offered people with disabilities the same or more 
privacy for voting than offered to other voters. 

Almost All Polling Places Had an Accessible Voting System: 

All but one polling place we visited had an accessible voting system to 
facilitate private and independent voting for people with disabilities. 

* In all but a few polling places, the accessible voting system was a 
voting machine. 

- The accessible voting machines had special features for people with 
disabilities, such as an audio function to allow voters to listen to 
voting choices. 

- The most common type of accessible voting machine at polling places 
we visited was Automark, followed by Premier Accuvote. 

* However, close to 5 percent of polling places had an accessible 
voting machine that was not set up and powered on.[A] 

Note: We did not assess polling places’ legal compliance with HAVA 
accessible voting system requirements.

[A] The 95-percent confidence interval for this estimate is 2.8 to 8.3. 

29 Percent of Polling Places Had Voting Systems That Could Pose 
Challenges for Voters in Wheelchairs: 

While virtually all polling places had voting systems with accessible 
machines, 29 percent of polling places had machines located in voting 
stations that did not have the minimum height, width, or depth 
dimensions to position a wheelchair within the station.[A] 

* We did not ask GAO observers to determine if other accommodations 
could be made to assist voters in wheelchairs.

[A] Based on ADA Accessibility Guidelines for Buildings and Facilities; 
subject to a sampling error of plus or minus 11.4 percentage points at 
the 95-percent confidence level. Access to the voting area was 
restricted to GAO at 107 of 730 polling places, and therefore, 
observations were not collected for those locations. 

Figure 6: Most Polling Places Offered People with Disabilities the Same 
or More Privacy for Voting Than Offered to Other Voters: 

[Refer to PDF for image: pie-chart] 

Same or more privacy at accessible machines than voting stations for 
other voters: 77%; 
Less privacy at accessible machines than voting stations for other 
voters: 23%.

2008. 

Note: Subject to sampling error of plus or minus 7.8 percentage points 
at the 95-percent confidence level. This is based on our observations 
of level of privacy and does not represent a legal evaluation of HAVA 
compliance.

Next Steps: 

These findings are part of our broader study designed to: 

* provide additional detail on polling places with features that might 
facilitate or impede voting for people with disabilities, 

* identify states’ actions to facilitate voting access for people with 
disabilities, and; 

* describe the steps Justice has taken to enforce HAVA voting access 
provisions. 

We plan to issue a report on this broader voting access study in late 
September 2009. 

We also plan to issue a report on voting practices for residents in 
long-term care facilities in late November 2009.

Appendix I: 

Selected a Nationwide Sample of Polling Places Using a Two-Stage 
Approach: Stage One: 

We selected a random sample of counties in the contiguous United States 
with probability proportionate to their total population. We made 100 
selections with replacement from the list of counties. We excluded 
Alaska and Hawaii for cost and efficiency reasons and Oregon because 
its voters exclusively use mail-in ballots. 

This method allowed the possibility for counties to be selected more 
than once and allowed us to select a sample that was representative of 
polling places on Election Day. Out of 100 selections, we ended up with 
a final selection of 84 unique counties across 31 states. 

Selected a Nationwide Sample of Polling Places Using a Two-Stage 
Approach: Stage Two: 

We chose a random sample of 8 polling places from each county for each 
time it was selected in stage one.[A] For example, we selected 8 
polling places if a county was selected once, and 16 polling places if 
it was selected twice. 

Each set of 8 polling places was assigned to a team of two GAO staff. 

[A] In two counties, less than 8 polling places were selected:one 
county only had 3 polling places because it is located in a primarily 
vote-by-mail state, and in another county, 1 of the 8 polling places 
was a mail-in only location. 

Arranged Access to Polling Places on Election Day: 

We contacted state and local election officials to obtain permission to 
visit polling places selected in our sample on Election Day. 

* GAO received approval from 79 of the 84 unique counties in our 
sample.[A] 

* In several counties, state or county officials granted us access but 
asked us not to enter the voting area or to wait to interview polling 
place officials until after Election Day.

[A] One county where we did not gain access was selected twice in our 
sample. 

Conducted Polling Place Visits on Election Day 2008: 

GAO teams (composed of two GAO staff) visited polling places on 
Election Day—November 4, 2008—to take measurements, make observations, 
and conduct a short interview with chief polling place officials. Some 
of these measurements include: 

* Slope of ramps or cut curbs are no steeper than 1:12; 

* Surface is paved or has no abrupt change over ½ inch; 

* Single-or double-door openings are 32 inches or wider. 

GAO teams visited 730 of 746 (98 percent) of the polling places where 
we had been granted access. 

We performed our work from April 2008 to April 2009 in accordance with 
generally accepted government auditing standards.

Appendix II: Scope and Methodology:

This appendix provides more details about our methodology for selecting 
our sample of polling places, conducting our 2008 Election Day site 
visits, updating the data collection instrument (DCI), and analyzing 
Election Day data.

Selection of Polling Places:

We used a two-stage sampling method to select the polling places that 
we visited on Election Day--November 4, 2008. In stage one, we selected 
a sample of counties. Each county we selected was treated as a 
"cluster" of polling places. In stage two, we selected a sample of 
polling places from within each county.

Since there is no central list of all of the polling places in the 
United States, the first stage of our sampling method started with all 
counties, because most elections are administered at the county level. 
[Footnote 15] For cost and efficiency reasons, we confined our list of 
counties to those in the contiguous United States, including the 
District of Columbia, thus excluding Alaska and Hawaii. We also 
excluded Oregon because eligible residents have voted almost 
exclusively by mail since 1998. The total number of counties from which 
we sampled was 3,074. The list of county population sizes was 
constructed from 2005 American Community Survey data. We used 
jurisdictions' total population size to define the probability of 
selection in the first stage of sampling because these census data were 
readily available for all counties and county equivalents. Although it 
would have been useful to define the sample using national data on all 
registered voters or all eligible voters, we did not use numbers of 
registered voters because census data on registered voters were not 
available at the county level nationwide. In addition, we did not use 
numbers of eligible voters (individuals 18 years old and over) because 
census data allowing us to exclude noncitizens and felons--groups that 
are not eligible to vote--from the 18 years and over population were 
also not available at the county level nationwide.

Because polling places were the unit of our analysis, we used a 
sampling method known as probability proportionate to size with 
replacement. In this method, the probability of selecting any county, 
or cluster, varies with the size of the county, giving larger counties 
a greater probability of selection and smaller counties a lower 
probability. The measure of size is the population of the county 
divided by the total population of all the states in our sample. Each 
time a county was selected, we returned it to the sample universe, 
which gave it an additional chance of being selected. Therefore, it was 
possible that we could select any one county multiple times in the 
sample. This method allowed us to select a sample that was 
representative of polling places across the country on Election Day. 
Using this sampling method, we selected a total of 84 unique counties 
in 31 states, or the equivalent of 100 counties, with 12 counties being 
selected more than once.[Footnote 16]

In the second stage, we selected a random sample of polling places in 
each county selected in stage one. To do this, we searched the Internet 
to see if each county posted a listing of its polling places. If so, we 
downloaded the list.[Footnote 17] If not, we contacted county or state 
officials to obtain a list of polling places. For each county list, we 
selected a random sample of eight polling places for each time the 
county was selected in our sample. For example, if a county was 
selected once, we selected 8 polling places, and if a county was 
selected two times, we selected 16 polling places. Election officials 
in 79 of 84 unique counties (the equivalent of 94 of 100 counties) in 
our sample granted us permission to visit on Election Day,[Footnote 18] 
for a total of 746 polling places.[Footnote 19]

Description of Site Visits and the DCI:

On Election Day, November 4, 2008, GAO sent out teams of two GAO staff 
to counties in our sample.[Footnote 20] Each team was equipped with a 
DCI on which to record their observations and the necessary measurement 
tools: the ADA Accessibility Stick IITM, a fish scale, and a tape 
measure.[Footnote 21] GAO monitored the activities of the teams 
throughout Election Day and provided assistance by telephone from our 
Washington, D.C. headquarters.

To ensure uniform data collection across the country, we trained all 
teams in how to:

* properly fill out each question on the DCI,

* use the necessary measurement tools, and:

* interview the chief poll worker in each polling place about the 
accessible voting systems as well as accommodations for voters with 
disabilities.

We also instructed teams on the appropriate times for visiting polling 
places and not to approach voters or interfere with the voting process 
in any way during their visits.

Each GAO team that visited a county on Election Day received a list of 
up to eight polling places to visit.[Footnote 22] The first polling 
place on their list was randomly determined. We then used geocoding 
software and the address of the polling places to determine the 
latitude and longitude coordinates for all of the polling places they 
were scheduled to visit. The latitude and longitude coordinates were 
used to determine the ordering after the first polling place, which 
minimized the net travel distance. This geocoding of the addresses 
allowed the GAO audit teams to minimize the travel distance between 
their polling places on Election Day. To maintain the integrity of the 
data collection process, GAO teams were instructed not to disclose the 
location of the selected polling places ahead of time.

In some cases, states or counties placed restrictions on our visits to 
polling places. For example, laws in some states prohibit nonelection 
officials from entering the voting room or voting area. Election 
officials in several counties granted us access on the condition that 
we not interview polling place officials on Election Day, and in 
several polling places, officials were too busy assisting voters to be 
interviewed.[Footnote 23] In these cases, we e-mailed and/or called 
chief polling place officials after Election Day to complete the 
interview. Polling place officials contacted after Election Day were 
asked the same questions as the officials interviewed on Election Day. 
Due to constraints of time and geography, some teams were not able to 
visit all eight polling places, but overall, GAO teams were able to 
visit 98 percent of randomly selected polling places, or 730 of 746 
polling places in 79 counties across 31 states.

GAO teams used a DCI that was similar to the one used in our 2000 study 
of polling places to record observations and measurements taken inside 
and outside of the polling place and capture responses from our 
interviews with chief polling place officials. However, we updated the 
DCI based on changes that have occurred in federal laws and guidance 
since 2000. The primary sources we used to determine the most current 
requirements and standards for evaluating polling place accessibility 
were the voting system requirements specified in the Help America Vote 
Act of 2002 (HAVA)[Footnote 24] and polling place accessibility 
guidance in the Americans with Disabilities Act: ADA Checklist for 
Polling Places, issued by the Department of Justice in 2004.[Footnote 
25] In addition, disability advocates and representatives of the U.S. 
Access Board reviewed a draft version of our DCI, and we incorporated 
their comments as appropriate. We also received input from officials of 
the Department of Justice, Election Assistance Commission, and national 
organizations that represented election officials. Finally, to ensure 
that GAO teams could fill out the instrument in the field and complete 
it in a reasonable amount of time, we pretested the DCI during the 
presidential primary election in South Dakota in June 2008 and the 
congressional primary election in Wisconsin in September 2008.

Analysis of Election Day Data:

In analyzing the data collected on Election Day, we first examined 
features that might facilitate or impede access on the path to the 
voting area.[Footnote 26] In doing so, we looked at features at four 
different locations at the polling place: the parking area, the path 
from the parking area to the building entrance, the building entrance, 
and the path from the building entrance to the voting area. These 
features included:

* Slope of ramps or cut curbs along the path are no steeper than 1:12.

* Surface is paved or has no abrupt changes over ½ inch.

* Doorway threshold does not exceed ½ inch in height.

* Single-or double-door openings are 32 inches or wider.

The percentage of polling places cited as having one or more potential 
impediments was based on whether or not a polling place was found to 
have at least one feature that might impede access to voting in any of 
the four locations we examined and does not include potential 
impediments associated with the voting area itself.

While features of the voting area were not included in our summary 
measure of whether a polling place had a potential impediment, we did 
look for features that might facilitate or impede private and 
independent voting inside the voting area. We identified the types of 
voting methods available to voters with and without disabilities and 
took measurements of the voting station or table used by people with 
disabilities to determine whether wheelchairs could fit inside the 
station or under the table and whether equipment was within reach for 
wheelchair users. We collected information on the accessible voting 
systems required under HAVA to determine the extent to which the system 
had features that might facilitate voting for people with disabilities 
and allow them to vote privately and independently. We also briefly 
interviewed chief poll workers at most of the polling places we visited 
to find out whether curbside voting was available and how the poll 
workers would handle voter requests for assistance from a friend, 
relative, or election official.

Sampling Errors:

All sample surveys are subject to sampling error, which is the extent 
to which the survey results differ from what would have been obtained 
if the whole universe of polling places had been observed. Measures of 
sampling error are defined by two elements--the width of the confidence 
interval around the estimate (sometimes called precision of the 
estimate) and the confidence level at which the interval is computed. 
The confidence interval refers to the range of possible values for a 
given estimate, not just a single point. This interval is often 
expressed as a point estimate, plus or minus some value (the precision 
level). For example, a point estimate of 75 percent plus or minus 5 
percentage points means that the true population value is estimated to 
lie between 70 percent and 80 percent, at some specified level of 
confidence.

The confidence level of the estimate is a measure of the certainty that 
the true value lies within the range of the confidence interval. We 
calculated the sampling error for each statistical estimate in this 
report at the 95-percent confidence level and present this information 
throughout the report.

[2] GAO, Voters with Disabilities: Access to Polling Places and 
Alternative Voting Methods, [hyperlink, 
http://www.gao.gov/products/GAO-02-107] (Washington, D.C.: Oct. 15, 
2001). 

[3] GAO, Elderly Voters: Some Improvements in Voting Accessibility from 
2000 to 2004 Elections, but Gaps in Policy and Implementation Remain, 
[hyperlink, http://www.gao.gov/products/GAO-08-442T] (Washington, D.C.: 
Jan. 31, 2008).

[4] This report focuses on access to voting for people with physical 
disabilities, but does not specifically address access for voters with 
hearing impairments. It also does not address access to voter 
registration, in-person absentee voting, or early voting.

[5] We excluded Alaska and Hawaii for cost and efficiency reasons and 
Oregon because voters exclusively use mail-in ballots. 

[6] The 730 polling places we visited on Election Day were located in 
79 of the 84 counties we selected for our sample because 5 counties did 
not grant GAO access to polling places on Election Day. In addition, in 
several counties, state or county officials granted us access but 
placed restrictions on our visits, such as preventing us from entering 
the voting area. 

[7] To update our DCI, we reviewed relevant laws such as HAVA and 
documentation related to polling place accessibility, such as the 
Department of Justice, Civil Rights Division, Disability Rights 
Section, Americans with Disabilities Act: ADA Checklist for Polling 
Places (Washington, D.C., February 2004).

[8] The 95-percent confidence interval for 2000 data is 11.3 to 21.6 
and for 2008 data is 21.9 to 32.7. The difference between the 2000 and 
2008 estimates are statistically significant. 

[9] This data is subject to sampling error of plus or minus 8 
percentage points at the 95-percent confidence level.

[10] The 95-percent confidence interval for 2000 data is 22.8 to 36.2. 
The 95-percent confidence interval for 2008 data is 12.2 to 21.1. The 
difference between 2000 and 2008 data is statistically significant.

[11] This data is subject to sampling error of plus or minus 6.9 
percentage points at the 95-percent confidence level.

[12] For the building entrance data, the 95-percent confidence interval 
for 2000 data is 51.6 to 66.4 and for 2008 data is 16.7 to 34.2. The 
difference between 2000 and 2008 data is statistically significant.

[13] Based on ADA Accessibility Guidelines for Buildings and 
Facilities; subject to sampling error of plus or minus 11.4 percentage 
points at the 95-percent confidence level. Access to the voting area 
was restricted to GAO at 107 of 730 polling places, and therefore, 
observations were not collected for those locations.

[14] This data is subject to sampling error of plus or minus 7.8 
percentage points at the 95-percent confidence level. This is based on 
our observations of level of privacy and does not represent a legal 
evaluation of HAVA compliance.

[15] We selected counties and cities that are county-equivalents for 
census purposes. In eight counties in our sample, officials at the 
subcounty level, such as towns and cities, administer elections. 

[16] See appendix III for a list of the counties we visited. 

[17] In cases where we downloaded a list of polling places from the 
Internet, we confirmed with county election officials that this was the 
most current list. In counties where township or city officials 
administered elections, we contacted all townships or cities within the 
county and asked for their lists of polling places as well as their 
permission to visit polling places in their jurisdiction. 

[18] One county where we did not gain access was selected twice in our 
sample.

[19] Two counties had less than eight polling places: One county only 
had three polling places because it is in a primarily vote-by-mail 
state, and in another county, one of the eight polling places was a 
mail-in only location. 

[20] Representatives of state or county election officials accompanied 
GAO teams in six counties, but they did not participate in the team's 
observations or interviews with polling place officials.

[21] The ADA Accessibility Stick IITM is a tool designed to measure 
potential structural impediments in buildings and on walkways. It was 
designed and manufactured by Access, Inc., Lawrence, Kan. The fish 
scale was used to measure the force required to open a door and was 
included in our study as a pilot measure.

[22] The types of buildings used for polling places varied widely but 
typically included houses of worship, schools, libraries, courthouses, 
police or fire stations, and community centers.

[23] State or county election officials restricted GAO teams from 
interviewing polling place officials in 10 counties on Election Day, 
although we were allowed to interview officials in all but 1 county 
after Election Day.

[24] HAVA requires that each polling place have at least one voting 
system for use in federal elections that is accessible for voters with 
disabilities and provide the same opportunity for people with 
disabilities to vote privately and independently as afforded by voting 
systems available to other voters. 

[25] U.S. Department of Justice, Civil Rights Division, Disability 
Rights Section, Americans with Disabilities Act: ADA Checklist for 
Polling Places (Washington, D.C., February 2004). This checklist is a 
self-help survey that voting officials can use to determine whether a 
polling place has basic accessible features needed by most voters with 
disabilities.

[26] We did not assess polling places' legal compliance with HAVA 
accessible voting system requirements.
