Every ZIP Code's health estimates, with the uncertainty attached

40 CDC PLACES measures for 32,520 ZIP Codes, 29,923 cities and places, 3,143 counties and every state: obesity, diabetes, blood pressure, smoking, insurance, disability, mental distress and more, each with its 95% confidence interval and read against county, state and nation.

These are model-based estimates, not measurements. CDC PLACES applies a statistical model to national survey responses and Census population data to estimate what share of an area's adults report each condition or behaviour. CDC: "We do not produce estimates for individuals; only aggregated results for counties, places, census tracts, or ZCTAs."

CDC on comparisons: "It is not adequate to simply compare point estimates. The confidence intervals should also be considered, and some are very broad." This site says higher or lower only when two 95% confidence intervals do not overlap, and similar when they do. CDC also advises that the data "should not be used for ranking the overall health of any county, place, census tract, or ZCTA" and that the model "cannot detect effects due to local interventions".

How to read this site

PLACES is a CDC project that estimates, for every small area in the country, what share of adults report each of 40 conditions, behaviours, preventive services, disabilities and social needs. The estimates come from a statistical model fitted to the national Behavioral Risk Factor Surveillance System and applied to each area's Census population; no one surveyed your ZIP Code. Every figure therefore carries a 95% confidence interval, and this site never calls one area higher or lower than another unless the two intervals do not overlap. The guides explain the method, the intervals and what the figures cannot tell you; the 2025 release page lists what CDC changed this year.
