How we calculate this mix & the national home-value percentile below
Every tracked city in Puerto Rico is bucketed by population: small town under 10,000; mid-size 10,000–99,999; large 100,000–999,999; megacity 1,000,000+. The national home-value comparison below plots Puerto Rico's average tracked-city home value against all 52 US states/territories, ranked the same way as the per-city percentiles: the state's percentile is the share of states with a lower average home value.
