Where are the health problems occurring?

Surveillance data are analyzed by place to:

  • determine the geographic location of where a health indicator is occurring in a population (clinic, county, region, state, etc.) and
  • gain insight into the geographic variation within the population.

The PedNSS and PNSS Geographic Comparison Tables provide a quick comparison of prevalence of health indicators across population geographic units. The specific tables for the geographic units of nation, contributor (state, District of Columbia, U.S. territory, or tribal government), county, clinic, and region can be used to compare data from one geographic area to a neighboring area such as a state to its neighboring states or a county to other counties within the state.


The geographic tables also provide a ranking of the prevalence for each health indicator for one geographic area compared with those from the larger area to which it belongs, for example, a county to other counties in a state. The number one always indicates the area with the "best" prevalence which may be the lowest or highest percent depending on the health indicator. For example the lowest prevalence is the "best" for anemia and growth indicators, while the highest prevalence is the "best" for breastfeeding. Because the geographic areas are ranked from best to worst, the area with the worst ranking for a health indicator can also be quickly identified.
