How to read this map
CDC PLACES models the share of adults with each condition for every census tract, using national survey data combined with local demographics. We show each community area as the area-weighted average of the census tracts it covers, so an area spanning several tracts blends their rates by how much land each contributes. Higher means a greater share of adults affected. Switch measures with the tabs; the drawer shows the CDC 95% confidence interval and how many tracts were averaged.
These are modeled estimates, not a census of diagnoses — treat them as a well-grounded pattern of where burden concentrates, not an exact count. Because census tracts are drawn to roughly equal population, an area-weighted average across a community area’s tracts closely tracks a population-weighted one.
