NOTE TO CORRESPONDENTS
From: Jennifer Marks
Acting Chief, Public Information Office
Subject: Policy on Disseminating Census 2000 Supplementary Survey (C2SS) Data
Files to the Media
Following is the broad outline of the Census Bureau's plan for
disseminating Census 2000 Supplementary Survey (C2SS) data through the end
of the year.
The 700,000-household survey was conducted in 1,203 counties
simultaneously with last year's census and was designed to test the
operational feasibility of collecting long form-type data independently of
a decennial census. The survey, which used the American Community Survey's
questionnaire and methodology, was an operational success. Release of
these data precedes next year's scheduled release of Census 2000 long form
data products.
Regional Press Briefings/Embargoed Data Release General Guidance:
Regional C2SS press briefings for the media will tentatively take place in
each one of the Census Bureau's 12 regions on Nov. 14 and 15. The
briefings for credentialed media will be held at the following locations:
Canton, Ohio; Charleston, S.C.; Fort Wayne, Ind.; Hartford, Conn.;
Houston, Texas; New York (Bronx), N.Y.; Orlando, Fla.; Philadelphia, Pa.;
Phoenix, Ariz.; San Diego, Calif.; Spokane, Wash.; and Wichita, Kan.
Each one of the briefings provides area reporters the opportunity to ask
regional directors and Census Bureau subject matter experts questions
about C2SS and the local data being released.
To allow sufficient time to fully understand the data set and
comparability issues, the Census Bureau will release on an embargoed basis
the C2SS data for substate areas most cities (64) and counties (216) of
250,000 population or more. The embargo period would begin at 9 a.m. on
Wednesday, Nov. 14, with public release of the data on Tuesday, Nov. 20,
at 12:01 a.m.
As was the case with the dissemination of previous census data, a product
announcement will be distributed once the data are placed on the Public
Information Office's Internet embargo page <http://www.census.gov/dcmd/
www/embargo/embargo.html>. To link to the FTP server where the data
and related materials will reside, bona fide media should enter the
Internet embargo page and click on "Census 2000 Supplementary Survey."
User ID/password remains the same as prior data releases and is posted on
the embargoed news release page.
Technical Documentation:
The formats for the 107 core tables and other documentation
for the C2SS release are currently available on the Census Bureau's FTP server
<http://www2.census.gov/census_2000/datasets/Census_2000_Supplementary_Survey>,
and the C2SS Web site <http://www.census.gov/c2ss/www>. The data will be
released in Microsoft Excel (.xls) format and in both narrative and
tabular profiles.
All C2SS data can be accessed on Tuesday, Nov. 20, via the Census Bureau's
Web site and the following URLs:
- The Census Bureau FTP server

Comparability
The C2SS data provide a way to understand how some characteristics and
aspects of the country changed during the 1990s at the national and state
levels. However, we recommend comparisons not be made at substate levels
between C2SS estimates and the 1990 census because the local data magnify
the survey's methodological differences and omission of group quarters
populations more so than higher geographies. Rather, cities or counties of
250,000 people or more should be compared within the C2SS data set either
with their state estimates, or with other substate geographies being
released.
These data are an example of what the American Community Survey will be
able to produce for the nation, states and small geographic areas. By
2004, the American Community Survey and its larger 3 million annual
household sample size will produce estimates for geographic areas and
population groups of 65,000 or more, and by 2008, for even the smallest
areas and population groups in the country.
Additional Census 2000 Supplementary Survey Data Releases:
The third and final release of C2SS data is scheduled for this winter.
The release will include the balance of about 700 additional tables,
including iterations by race for the country, each of the 50 states, the
District of Columbia and most cities and counties with populations of
250,000 or more.
