In developing countries like India death rates have also decreased but birth rates have remained extremely high.
Birth rates are high because:
- Children are needed to work and bring in an income for the family.
- Children are required to look after elderly parents because of a lack of pensions.
- Lack of availability and knowledge of contraception and family planning.
- High infant mortality rates, so parents have more children in the hope that some survive.
- Religious beliefs – certain religions encourage large families.
- In some developing countries, children can be viewed as a status sign for men.
Death rates are fairly high because of:
- Lack of food caused by famine.
- Poor sanitation and lack of clean drinking water.
- Natural disasters destroying crops.
- High levels of disease, eg malaria.
- Lack of doctors, medicines and healthcare.
- War, eg Afghanistan.
As birth rates are higher than death rates there is rapid population growth in developing countries.
