Unwed childbearing has increased dramatically, regardless of mother's age
Today, nearly nine in 10 children born to teenage mothers are born outside of marriage - a more than six-fold increase since 1950. The increase among mothers in their early twenties was especially pronounced: a 16-fold jump. The increase among unwed mothers age 30 and older is at least 10-fold.
