Census survey estimates, 2020–2024 ACS five-year vintage 2024. Effective rate here means median annual real estate taxes paid (B25103) divided by median owner-occupied home value (B25077). Owner-occupied units come from B25003. This is a ratio of two medians, not a statutory rate or the median of individual homeowners’ rates.

Survey estimates have sampling error. Countywide medians do not account for a particular home’s condition, assessment rules, exemptions or taxing districts. Rankings describe point estimates, not statistically significant differences. Missing and bounded estimates are excluded from rates and rankings.
