The birthrate in most of developing countries is higher than in developed ones. Here are some reasons :
- Women have little control over their lives. They don't always have access to birth control.
- Less developed countries depend on farming, and to do that, families need more children to work in the farms. The more children you have, the more workers you'll have.
- Abortion is not readily available.
- Religious and/or cultural point of views encourage more children.
- Sad but true, in many cultures, boys are valued more than girls, so the couples who start off with girls will keep having babies until they have a boy.
