What is the ranking?

What stands out?

The 100th city on the list uses 22 ZIP codes. Big cities have many because each delivery area, post office and large institution can have its own code. Population explains much of the ranking, but not all of it: a place with a large unincorporated area or several post offices can have more codes than a larger compact city. See how ZIP codes work.

Geographically, the 100 places on this list are spread over 42 states and territories. The most represented are California 9; Texas 9; New York 8; Ohio 5; North Carolina 4; Tennessee 4. By time zone, the split is Eastern 42, Central 33, Pacific 13, Mountain 9. The county that appears most often is Los Angeles County, CA, with 3 entries. Patterns like these show which regions produce the extreme values in the ranking, and they change if you tighten or loosen the population cutoff.

Are small towns included? Only places with at least 5,000 residents in our data have a page and a ranking, so very small communities are not shown. They still appear on county pages.

Is this an official ranking? No. It is calculated from one dataset using estimates, and official rankings from the Census Bureau can differ because of different boundaries and years.

How is this list made?

The data comes from the SimpleMaps US Cities Database. Population is an estimate, and density is converted from people per square kilometer to people per square mile. Estimates for large cities can reflect the wider urban area rather than the legal city limits, so use the lists to compare places inside one dataset rather than as official counts. See why population figures differ, and check the Census Bureau for official figures. The rankings are rebuilt whenever the site is regenerated from a newer copy of the data, so the date shown on the guides and legal pages tells you roughly how fresh they are. If you spot a result that looks wrong, please send us a correction with the page address.
