How dense are the cities in Missouri?

Which counties do the top 50 belong to?

Quick answers about Missouri cities

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. Read why population figures differ and how density is calculated before you quote a number.
