Owner-occupied homes, five-year estimates 2020-2024; 90% margins of error as published. “Tax ÷ value” is the median tax divided by the median value, a ratio of two medians. The Census caps reported taxes at $10,000 and values at $2,000,000: where a median hits the cap, the ratio is approximate. In small counties the margin of error can be large.
