These new data suggest that the trend is continuing, as the report shows that between 1980 and 2017, the abortion rate for females between the ages of 15 and 19 fell by more than 82 percent. The abortion rate for 35-to-39-year-olds fell by only 8.5 percent during the same timespan.

The large reduction in the teen abortion rate is partly the result of a higher percentage of pregnant teenagers choosing life for their preborn children. According to these new statistics, the percentage of pregnancies carried to term by women ages 15 to 19 between 1980 and 2017 increased by more than 10 percent.

An even more important reason for the drop in the teen abortion rate is that teenagers are now much less likely to become pregnant in the first place. According to Guttmacher, the teen pregnancy rate peaked in 1990 at 117.6 pregnancies per thousand teenaged females (girls 15 to 19). Since then, the teen pregnancy rate has declined by a whopping 73 percent.
