This is a mixed-methods dataset. The study explored attitudes towards, and experience of, the markets for migrant domestic and sex workers in the UK and Spain through a combination of interview and survey research. The interviews were structured around a standard set of topics, and examined respondents' attitudes towards gender, race/ethnicity, age, and domestic work/commercial sex. It aimed to examine continuities and discontinuities between domestic work and sex work, paying particular attention to the role of the social/cultural imagination in constructing a market for migrant workers and questions about how this demand relates to broader socially tolerated attitudes towards race, gender, age and sexuality, and to make a contribution to current theorizing on gender, nationality, global interdependence, age, racial/ethnic identities and the complex intersections among these systems. Reasons for employing domestic workers; attitudes towards employment relations with domestic workers Experience of commercial sex; attitudes towards gender and sexuality; attitudes towards/beliefs about migrant sex workers
