This document summarizes China's population control policies and their implementation since 1949, with a focus on the concept of "illegal pregnancy". Key points:
- China introduced a one-child policy in 1979 to control population growth, defining legal births according to family eligibility rules and local quotas.
- A pregnancy is considered "illegal" if a woman does not have permission from population authorities. Permissions depend on family planning rules and birth targets.
- Implementation involves surveillance of married women, incentives for compliance, and penalties for illegal pregnancies including fines exceeding annual income.
- Abortions increased after 1979 and many pregnancies ended in abortion depending on their legal status. Data also show an imbalance in registered birth sex
