I knew teen pregnancies were declining in the USA. Didn't realize that:
A) the rate was over 100/1000 at times in some states in the late 80s
B) the rate has declined by as much as an order of magnitude
C) CA used to have the highest rate (98/1000 in '88; 13/1000 in 2017).
D) North Dakota had the lowest rate in late 80s (24/1000 in '88; 13/1000 in 2016).

Pregnancies, Births and Abortions in the United States, 1973–2017: National and State Trends by Age
The Guttmacher Institute calculates comprehensive historical statistics on the incidence of pregnancy, birth and abortion for people of reproductive age in the United States (see Definitions). Our most recent release includes national statistics covering the period from 1973 to 2017, the most recent year for which comparable data are available; state-level statistics are available for selected years from 1988 to 2017 (see Note).
