How is this ranking made?

The data comes from the SimpleMaps US Cities Database, which gives each place an estimated population and a density in people per square kilometer. We convert density to people per square mile and rank the places with at least 5,000 residents. Boundaries matter: a city that includes large parks or farmland scores lower on density than a compact city of the same size, and population estimates can include areas that share a city's ZIP codes.
