The associating factors of hiring domestic help have not been thoroughly studied in a non-Western context. Using household survey data (N = 974), this article investigates the interactive role of gender attitude and women’s income on the decision to hire domestic help in Hong Kong. Some previous studies fall short in finding a significant association between respondents’ gender attitudes and the hiring of domestic help, while wives’ income is a consistent factor in the hiring of domestic help across a number of studies. In this study, we found that husbands’ traditional gender attitudes and wives’ high income sharply increase the likelihood of hiring domestic help. However, their associations with the hiring of domestic help are conditional on each other. In addition to women’s socioeconomic status, ideational factors should be taken into account in projecting local demand for domestic help and in understanding the increasing trend of domestic outsourcing.
