About this data

These figures come from Polco's GPAL data, which brings together public data on U.S. cities and counties from sources like the Census Bureau, the CDC, the Bureau of Labor Statistics and the FBI. Each number is for the year shown with it, and most public data runs one to two years behind. Dollar figures are not adjusted for inflation.

The comparisons are Polco's. Each one names the group of communities Suffern is compared with, and the percentile is Suffern's place within that group. Polco's model figures are estimates, not measurements.
