Using OLS regression we model predictors of housework hours for 393 Mexican origin and Anglo families from California and Arizona. Contradicting cultural theories, Mexican origin mothers performed less housework when they were employed more hours, had higher relative earnings, and when husbands had more education. Mexican origin fathers performed more housework when family income was lower, wives contributed a larger share of earnings, and fathers had more egalitarian gender ideals. Fathers’ employment hours, wives’ gender attitudes, and familism were not significantly associated with housework hours in Mexican origin families, but were significant in Anglo families. Unique features of the study include analysis of generational status, gatekeeping, and familism. Theoretical reasons for attitudes and socioeconomic status predicting housework are discussed.
