Final answer:
Birth rates are lower in developed countries for three main reasons: increased economic security, educating women, and greater access to contraception.
Step-by-step explanation:
There are three main reasons why birth rates are lower in developed countries:
- Increased economic security leads to a demographic shift where birth rates decline. When people have enough to eat and are no longer worried about starving in old age, they have fewer children.
- Educating women also contributes to lower birth rates. When women are educated and have access to opportunities, they tend to delay marriage and childbearing.
- Greater access to contraception and family planning knowledge can also result in lower birth rates. When people have better knowledge and access to contraception, they are able to plan and space their pregnancies more effectively.
