How to read this page
What these estimates cover.
Figures are five-year rolling averages from the American Community Survey, not single-year counts, so they describe conditions across 2019-2023 ACS 5-year rather than a single date. Median home value covers owner-occupied units as valued by their owners, and median gross rent includes utilities the renter pays. Small counties carry wide margins of error; treat single-dollar differences between neighbouring counties as noise.
