Median effective rate = total real estate taxes paid ÷ total home value, for owner-occupied housing (2024 American Community Survey). YoY change is the inflation-adjusted change in taxes paid, 2023–2024. "N/A" indicates the Census Bureau's sample size was too small for a reliable county-level estimate.
