“Here’s the take-away. From one scandalous pregnancy in a rural public high school in the 1970s, to many non-scandalous pregnancies in that same school by the 1990s:
And probably a lot fewer 20 years later.

“In 2015, a total of 229,715 babies were born to women aged 15–19 years, for a birth rate of 22.3 per 1,000 women in this age group.
This is another record low for U.S. teens and a drop of 8% from 2014. Birth rates fell 9% for women aged 15–17 years and 7% for women aged 18–19 years.”
“Although reasons for the declines are not totally clear, evidence suggests these declines are due to
more teens abstaining from sexual activity, and
more teens who are sexually active using birth control than in previous years.”
“In 2014, there were 24.2 births for every 1,000 adolescent females ages 15-19, or 249,078 babies born to females in this age group. Nearly 89 percent of these births occurred outside of marriage.”
“The 2014 teen birth rate indicates a decline of nine percent from 2013 when the birth rate was 26.5 per 1,000.1
The teen birth rate has declined almost continuously over the past 20 years.
In 1991, the U.S. teen birth rate was 61.8 births for every 1,000 adolescent females, compared with 24.2 births for every 1,000 adolescent females in 2014. Still, the U.S. teen birth rate is higher than that of many other developed countries, including Canada and the United Kingdom.”
"Teen birth rates differ substantially by age, racial and ethnic group, and region of the country.
Most adolescents who give birth are 18 or older; in 2014,
73 percent of all teen births occurred to 18- to 19-year-olds.1 Birth rates are also higher among Hispanic and black adolescents than among their white counterparts. In 2014, Hispanic adolescent females ages 15-19 had the highest birth rate (38 births per 1,000 adolescent females), followed by black adolescent females (34.9 births per 1,000 adolescent females) and white adolescent females (17.3 births per 1,000 adolescent females) (see Figure 1).1 Estimates from 2013 data show that 11 percent of adolescent females in the United States will give birth by her 20th birthday, with substantial differences by race/ethnicity: 8 percent of white adolescent females, 16 percent of black adolescent females, and 17 percent of Hispanic adolescent females.3
“Although Hispanics currently have the highest teen birth rates, they have also had a dramatic recent decline in rates. Since 2007, the teen birth rate has declined by 50% for Hispanics, compared with declines of 44% for blacks and 36% for whites.”
