In rural areas there tends to be a higher rate of fertility in order to provide workers for the farms in that area. In many rural regions, this theory is more accepted and recognized. Another factor that tends to influence the birth rates and fertility rates in many countries is welfare. Welfare provides support for mothers who are not working. A research survey was conducted in the United States, in order to determine if welfare had any effect on fertility.
Contraception has a major influence on birth rates and fertility.
The use of modern contraception has reduced birth rates significantly in developing countries. In less developed countries there are fewer reasons to use contraception. There is a decreased use of contraception in order to ensure this. In relation, there is also a correspondence with infant mortality. The approach taken for this research is the use of secondary data analysis.
