Effective rate = median real estate taxes paid ÷ median home value. Taxes are what homeowners report paying for the year; values are what they say the home would sell for. Where the Census Bureau caps the median tax at “$10,000+”, the rate is total taxes paid ÷ total home value instead. ± figures are the Census 90% margins of error.
