Notes: All models adjust for age, educational attainment, marital status, region, urban-rural residence, metropolitan statistical area classification, year, and person fixed effects. Model 2 further adjusts for additional children. Model 3 includes all the variables from Model 2, in addition to marital status and the spouse's hours and earnings.
