Where county property-tax estimates changed fastest
Across 3,121 counties with paired ACS estimates, the published median annual property-tax figure changed +23.6% on average between the 2020 and 2024 five-year releases. This report keeps the two values visible so a change can be checked rather than inferred from a current ranking.
What this comparison measures
Each row compares the same county-level median annual property-tax measure in two Census ACS five-year estimate vintages. It shows the difference between published estimates, not the cause of a household's bill: local assessment practice, exemptions, policy, and home-value changes can all matter.
The highlighted percentage charts exclude counties whose 2020 published median was below $500, because a small starting value can make a percentage ranking unstable. County profiles retain their complete five-year history.
Data coverage: 3,121 counties with a reported value in both vintages. Data as of .

Percentage decline among counties with a 2020 published median of at least $500. A decline is a change in the ACS estimate, not a finding about local tax policy.

How to use the release comparison
A county can show a large change in its published median estimate while still having a lower current effective rate than another county. Use this report to inspect the paired releases, then use the county profile for the current rate, home-value context, and the complete historical series.
ACS five-year estimates smooth several survey years and arrive with a publication lag. They are a comparable public-data benchmark, not a substitute for a current assessment notice, tax bill, or county assessor record.
