How the figures were made
The floor of 100,000 residents (Census Bureau estimate for 2025) keeps a small base from making a large percentage.
The county indexes are FHFA developmental annual indexes. A county has a row when its index has a value in every year to the newest year.
A program makes this page from the source files with fixed sentence rules. How the figures are made. Data sources and licenses.
