Notes: The n of cases varies due to missing data. Tests of significance are for differences by gender: t-test for continuous variables; χ² for binary variables. Figures given in Total, Women, and Men columns are means, with standard deviations in parentheses. The mean of a binary variable represents the percent of cases with that attribute. Standard deviations are omitted for binary variables.

^aThe reference category for marital status in all tables is married.
