2Multiply numbers by a thousand.
3Numbers within selected characteristics may not sum to total due to rounding.
All relative standard errors are <30% unless otherwise indicated.
*Relative standard error of the estimate is 30%–50%; the estimate is unreliable.
**Suppressed if relative standard error of the estimate exceeds 50% or if standard error is missing or 0.
