I kept Googling things like “US cities with population between 50,000 and 150,000” and not finding a clean answer. The results were listicles with no sourcing, scraped Wikipedia tables of unclear vintage, or instructions to download a raw Census file and figure it out yourself. None of them were the thing I actually wanted.
The thing I wanted was simple: pick a population band, get the list, see where each number came from, and download the result as a CSV. That should not be hard. It exists in the official data — the U.S. Census Bureau publishes annual subcounty population estimates — but the path from raw Census file to a usable filtered list is exactly the kind of work most people will not do.
So I built the version that should have existed. The audience is everyone I imagined was running the same search: researchers checking a figure, journalists framing a story, planners sizing a market, real-estate analysts comparing places, hobbyists curious about their state, anyone who wants the answer without trusting a random listicle.
The bar is straightforward. Every number on this site has to be re-derivable from a public Census file. No editorial population estimates, no “approximately,” no synthesized commentary about a city’s character. Just the data, the source, and the methodology.
