People do not have access to contraception(to prevent unwanted pregnancy); people are not educated about family planning(they are not taught how to avoid becoming pregnant); children can work e.g. on farms and bring money to their household; As there are often no pensions or care homes, parents rely on their kids to look after them when they get old; high infant mortality rates mean many children die young so people have large families to compensate; women are often not educated and have few career opportunities. They are expected to stay at home as housewives; women often get married very young so start having kids at young age; religions and cultures often promote large families and they are seen as a status symbol. Religions often discourage contraception.
