Adj., adjusted; CI, confidence interval.

All estimates are weighted.

Estimates adjusted by age, sex, and race/ethnicity using the projected 2000 U.S. population as the standard population.

a

Currently employed adults working only one job.

Estimates with a relative standard error >50% or based on cell sizes ≤10 are not shown as they do not meet standards of reliability/precision.

*

Estimates preceded by an asterisk have a relative standard error >30% and ≤50% and should be used with caution as they do not meet standards of reliability/precision.
