Exploring Gender Differences in Residential Water Demand

Residential water demand has been extensively studied, with the impact of various household characteristics on consumption well-documented. However, the specific effect of gender on household consumption remains insufficiently identified due to the predominant focus on mixed-gender households in previous research. In this paper, we aim to address this gap by examining gender differences in water consumption specifically within single-gender households. To accomplish this, we analyze data from 275 households equipped with individual meters in the city of Gijón, Spain, between 2017 and 2021. Our approach involves two main steps: first, the estimation of a Stone-Geary demand function for water consumption for both women and men single-gender households, and second, employ the Oaxaca-Blinder decomposition to examine gender differences based on the previous estimations. Our findings reveal that women’s households consume significantly more water compared to men’s households. Additionally, we observe that the demand for water is more inelastic among women, and their level of conditional use threshold is higher than that of men. Importantly, we find that these differences can be primarily attributed to distinct factors such as family composition, housing characteristics, and bill information between genders.
