Context: Public health is a large and expensive problem for policymakers to understand in order to provide health services and prevent future epidemics. Self-reported data can be tricky due to many sampling issues, but it can paint an interesting picture of how healthy a given area’s population might be. Content: Data includes small area samples of residents from 500 US cities. Recorded is the percent of residents who answered a public health-related question affirmatively (see [here](https://nccd.cdc.gov/500_Cities/rdPage.aspx?rdReport=DPH_500_Cities.ComparisonReport)). In addition to crude data, additional data is provided with age adjustment applied. 95% Confidence Intervals also provided for both datapoints.
