This document compares household registration systems in China and France. China's hukou system restricts internal migration and limits access to welfare benefits based on one's place of registration. France's system of etat civil and livret de famille records individuals' civil status without restrictions on movement. Both systems aim to identify individuals and collect population statistics. While France's system is person-based, China's is still tied to one's hukou status and location. The document discusses reforms to China's system to promote mobility and balanced economic growth.
