Census metric ranks compare all jurisdictions in this snapshot (typically 50 states plus D.C.). Race and ethnicity categories follow Census definitions (e.g., Hispanic origin is asked separately from race). Percentages are shares of total population and may not sum to 100% because of rounding or other groups. State–local tax burden is not a Census figure; see the Tax Foundation link below for 50-state + D.C. rankings (1 = lowest aggregate burden).
