How CountySet works
CountySet puts public data about every U.S. county on one map, so you can see where a place stands and find places like it.
Where the numbers come from
Every dataset comes from a public source such as the Census Bureau, the CDC or the USDA. The number you see for a county is the number that source published. Under the map's legend, About this data names the source, the period it covers, how it was measured and what to keep in mind.
Some counties have no number. CountySet keeps three cases apart: no data, suppressed (the source withheld it, usually because there were too few cases to publish safely) and doesn't apply. All three are grey, so a missing county never looks like a low one.
The four ways to look
- Explore colors every county by one metric. Click a county for its profile: the traits where it stands out most, and buttons to find similar counties.
- Filter shows the counties that meet every range you set.
- Seek ranks counties by how well they fit what you care about, with your own weights.
- Correlation shows how two metrics move together across counties.
What the comparisons mean
"Higher than 92% of counties" means 92% of the other counties with data have a lower value. It says where a county sits, not whether that's good or bad. Similar counties are found by comparing how far each county is from the average on the same metrics; the closer the pattern, the more similar.
Free and premium
Everything on CountySet is free today. Later, some extra datasets and tools will be part of a paid plan.
