aModel 1 contains terms for race/ethnicity, and the interaction between race/ethnicity and segregation. bModel 1 plus level I Omernik ecoregion; average annual rainfall ( < 10", 10"–19", 20"–29", 30"–39", 40"–49", ≥ 50" ); and average rainfall in driest month (0", < 1", 1" to 2", 2" to 3", ≥ 3" ). cModel 2 plus owner-occupied vs. rented housing units; household income below poverty, between poverty and 2× poverty, or at least twice poverty level. dModel 2 plus block group population density (2,000–3,999/km2, 4,000–5,999/km2, 6,000–7,999/km2, 8,000–11,999/km2, 12,000/km2 and higher); CBSA population size (100,000–249,999, 250,000–499,999, 500,000–999,999, 1,000,000–2,499,999, 2,500,000–4,999,999, ≥ 5,000,000).
