China - Case Study - Controlling Population


Late Long and Few - Have children later and longer gaps between them. Fertility rate fell, but population still growing

One Child Policy - 
If you only have one child: longer maternity leave, better housing, free education

If you have more than one child: fined part of income, no benefits

Changes: Rural areas - more than one if first born is a girl or has a disability

If both parents are only children/1 parent has a disability = can have 2 children

Migration Laws - tight migration laws so hardly any people migrate there and increase population
