A figure that looks wrong

Every number on a state page or in a tool answer has a source line under it that names the publisher and the data year. Check that line first: a county’s own website often quotes a newer or older year than the one shown here, and the two can both be right. If the figure still looks wrong, send:

• the page address (for example countyatlas.org/us/ohio)
• the county and the field, such as population, median household income, unemployment or county seat
• the value the page shows and the value you expected
• where your value comes from, ideally a link to the county’s or the state’s own page

Each report is traced back to the source file. A confirmed error is corrected in the data and the page; if the source itself says what the page says, the reply explains which source and year it is. The methodology lists every source and the rules for when a figure is left blank.

A tool that gave the wrong answer

The location tools ask the U.S. Census Bureau’s geocoder and its official boundaries. Most wrong answers come from an imprecise location or an address that matched the wrong street, so these details help most:

• which tool you used (county, city, state, township, congressional district or ZIP lookup)
• what you entered, or that you pressed Use my location. You don’t need to send your exact address; the nearest cross streets and the town are enough to reproduce most errors.
• what the tool answered and what you expected
• your browser and device, for example Safari on an iPhone, because location access works differently in each
• a screenshot, if you have one

What this site can’t help with

CountyAtlas publishes maps and statistics. It can’t answer questions about a tax bill, a voter registration, a property line or a court case. The county’s own offices handle those; the county finder tells you which county to ask.

Who runs CountyAtlas

CountyAtlas is built and run by Marko Visic (BSc Physics, University of Ljubljana). The figures come from federal sources (the U.S. Census Bureau, the Bureau of Labor Statistics and HUD) plus Wikidata for county seats, with the seats Wikidata lacks taken from the pages cited in the seat file. More on the about page.

Reuse and privacy

The dataset is federal public-domain data plus Wikidata (CC0) and the cited county seats. Reuse notes are on the data page and in the disclaimer. The privacy policy explains how your data is handled and how to ask for access, correction or deletion; send those requests to the same address.
