The studies of descriptive political representation demonstrate that the share of women amongst local elected officials increases, but mayors are still predominantly men. This paper contributes to the literature on the link between the descriptive and substantive representation of women at the local level. It investigates the influence of mayors’ gender on the development of local childcare policies in Poland. We employ quasi-experimental research schemes (difference-in-differences and generalised synthetic control) to study changes in childcare provision and public spending on nurseries and kindergartens. We merged electoral data (changes on the mayoral position) and registry data on local budget expenditures and service availability covering a period of more than 16 years. We do not find any systematic causal link, suggested by the extant literature on substantive representation, between the election of a female mayor and the expansion of childcare services.
