What is the reason for the long-term low growth rate of French population?

The reasons for the low population growth rate in modern France are mainly the low birth rate and the high death rate caused by the war. The main reason for the low birth rate in modern France is that people from all walks of life are unwilling to have more children. Affected by the small-scale peasant economy, the majority of small farmers are reluctant to subdivide a small piece of land to future generations; The small and medium-sized rentier class, who make a living by cutting coupons, try to maintain their original living standards; Some workers responded to the initiative of some trade unions to implement a "belly strike" and had low birth expectations. In modern France, the political situation was unstable, and wars often took place with neighboring countries. Others immigrated to America. Modern France, like after World War II, like western European countries, has maintained a low fertility rate for a long time after a short birth peak. First of all, due to the development of contraceptive technology, people can choose the number of children according to their own wishes, which provides the primary condition for the low birth rate. However, the perfect social security system from cradle to grave in developed countries has subverted the traditional concept of "raising children to prevent old age", and the era of "more children and more happiness" has passed. In addition, the high divorce rate, personal economic burden and living cost are also the reasons for the low fertility rate.
