Adaptation to heat is a major challenge for the Paris region (France). Based on fine-scale data for the 1,287 municipalities of the region over 2000–2017, we analyzed (time-serie design) the temperature-mortality relationship by territories (urban, suburban, rural), age (15–64 and ≥ 65) and sex, and explored how it was modified by vegetation and socio-economic indicators. Heat was associated with an increased mortality risk for all territories, age groups, sex, and mortality causes. Women aged 65 and over residing in the most deprived municipalities had a relative risk (RR) of deaths at 29.4 °C (compared to 16.6 °C) of 4.2 [3.8:4.5], while the RR was 3.4 [3.2:3.7] for women living in less deprived municipalities. Actions to reduce such sex and social inequities should be central in heat adaptation policy. •In the Paris region, heat-mortality risks are similar in urban and rural settings.•Vegetation reduces the heat-mortality risk for the 15–64 years old, especially for men.•Social deprivation increases the heat-mortality risk, especially for women.•Reducing sex and social inequities is critical to heat adaptation.
