Evidence: Supports the 2020–2024 vacant housing-unit count values and labels for the listed county and county-equivalent geographies.
The 5-year estimates pool survey responses collected from 2020 through 2024 and are not a single-year 2024 snapshot. County geography includes county equivalents such as independent cities. Values count housing units classified as vacant at the time covered by the survey estimate. The values are absolute counts rather than rates or shares. ACS estimates are subject to sampling error; margins of error are not included here.
The ranking uses the 2020–2024 American Community Survey 5-year estimate for vacant housing-unit count across U.S. counties and county equivalents. Values are ordered from highest to lowest, with equal values retaining tied ranks. National, state and other summary geographies are excluded. Compact labels are rounded for readability without changing the source order.
All entries use the same Census source family, ACS 5-year product, 2020–2024 period and measurement unit (housing units), supporting a like-for-like ranking across the stated county geographies.
