France Faces Declining Ideal Family Size Amid Changing Demographics

A significant decline in the ideal family size in France raises demographic concerns.

Key Points

  • • Ideal family size in France has decreased from 2.7 to 2.3 children over 25 years.
  • • In 2024, a survey showed a preference for smaller families among 12,800 French adults.
  • • For the first time since 1945, more deaths than births were recorded in France from May 2024 to May 2025.
  • • The summer heatwave in 2025 caused 480 excess deaths.

Recent data indicates a significant decline in the ideal family size among the French population, dropping from an average of 2.7 children two decades ago to 2.3 children today. This finding emerges from a comprehensive survey conducted by the Institut national d’études démographiques (Ined) in 2024, which revealed that the sentiment for fewer children is prevalent among 12,800 respondents.

The disturbing demographic shift is underscored by France's recent milestone, where the country recorded more deaths than births between May 2024 and May 2025, a first since 1945. This was further complicated by a summer heatwave in 2025, leading to 480 additional fatalities. The changing family dynamics are echoed by a decrease in the average age of women giving birth to their first child, signaling a broader evolution in societal views on family planning.

Experts point to these trends as indicators of shifting priorities, with economic considerations, lifestyle choices, and climate concerns all playing significant roles. The implications of these changes raise questions about the long-term demographic landscape of France, emphasizing the urgent need for policy discussions around family support and welfare.
