|||||||||||||||||||||||
Use the Geographic Comparison Tables to compare overall
prevalence for health indicators from one geographic area (clinic, county,
contributor, etc.) to the overall prevalence for the same indicators for
another area.
Only the geographic tables for health indicators are produced at all levels:
The report for the Nation (D) includes the overall prevalence for each contributor included in the national report.
PedNSS Geographic Comparison of Health Indicators tables include:
PNSS Geographic Comparison of Health Indicators tables include:
These tables can be used to answer questions such as:
The following paragraphs provide general information about the table data that will help you with interpretation.
Title
For PedNSS, the table titles show the health indicators that are analyzed in
the table.
For PNSS, the table title includes a group of health indicators but only
selected health indicators are included in the group.
Review the
PNSS table titles.
Ranking
The prevalence of the health indicator is ranked numerically from best to
worst to simplify identification of the geographic area with the best or
worst ranking. The numerical ranking is shown in parentheses next to the
prevalence. A ranking of (1) always indicates the geographic area with the
“best” (or most desirable) prevalence. For some indicators, the most
desirable prevalence is the highest value; for other indicators, the most
desirable prevalence is the lowest value. For example:
We're going to look at sections of the PedNSS Table 6B Geographic Comparison of Health Indicators. You can click on the View Sample Table link below each portion to review the entire table. The sample table is numbered to match the portions shown below.
This “B” or county-level table includes the prevalence
of birthweight for each county in the state. The number in parentheses next to the prevalence is the numerical ranking. In this instance, a ranking of (1) indicates the geographic area with the “best” prevalence. For example, in Adams county, 188 records are included in the analysis for Birthweight; the prevalence of Low for this age group is 4%. Adams county is ranked as (1). An * (asterisk) for the prevalence of Low and High Birthweight in Alexander county indicates that fewer than 100 records are available for analysis after exclusions. Prevalence is not calculated for health indicators with less than 100 records. |
Review the definition of Birthweight and its prevalence calculation.
If multiple geographic areas have the same prevalence, they are
ranked equally. For example:

The last two rows of the report provide a state and national PedNSS comparison. |
