On Sunday, September 27, 2026, 178 of the 348 seats in the French Senate were filled in a partial renewal. The newly elected senators form a chamber that is slightly younger than its predecessor, with an average age of 60 years and 1 month, down from 62 years and 5 months. In contrast, the National Assembly, France’s lower house of parliament, has an average age of about 49 years. Over 83% of the new senators are over 50, with the largest group aged 60 to 69, totaling 135 individuals. Mathilde Ollivier, an ecologist and senator representing French citizens abroad, is the youngest member at 32 years and 3 months. At the other end of the spectrum, Pierre Cuypers, a senator from Seine-et-Marne affiliated with the LR (Les Républicains) party, is the eldest at 82 years and 6 months, succeeding Alain Chatillon, who had been 83 years and 6 months old at the end of his term. In terms of gender representation, the new Senate includes 134 women, or 38.5% of its members, which is one elected woman fewer than in the previous renewal. This percentage is slightly higher than the 36.1% of female deputies in the National Assembly following the 2024 early legislative elections. However, the share of women remains significantly lower than that of men, with a ratio of seven female senators for every 11 male senators. Although the list voting system requires an alternation of men and women on candidate lists in constituencies that elect more than three senators, men still dominate the top positions on these lists in 64% of cases, which may give them an advantage in securing seats. The professional backgrounds of the senators reflect a mix of experience and diversity. Slightly more than 50% of the chamber (176 members) belongs to the socio-professional category of managers and higher intellectual professions. Approximately 12.6% (44 members) are retired, and 7.2% hold intermediate positions (25 members), typically covering employees. The Senate also includes 12 farmers, highlighting its traditional association with rural areas. Among the newly elected senators, 111 were re-elected for a new term, while 67 entered the Palais du Luxembourg, the Senate’s headquarters, resulting in a renewal rate of 37.6%. However, 23 senators who ran for their seats did not meet the required threshold to be elected.
