Teenage pregnancy
Worldwide, rates of teenage births range widely. For example, sub-Saharan Africa has a high proportion of teenage mothers whereas industrialized Asian countries such as South Korea and Japan have very low rates. Teenage pregnancy in developed countries is usually outside of marriage, and carries a social stigma; teenage mothers and their children in developed countries show lower educational levels, higher rates of poverty, and other poorer "life outcomes" compared with older mothers and their children. In the developing world, teenage pregnancy is usually within marriage and does not carry such a stigma.
