> In 1957 it was 96/100k teen women had babies, 62/100k in 1991 and now down to the current rate of 11/100k
That's per 1k, not 100k [1]. 96/100k would be an insignificant amount. 96/1000 of girls and women ages 15-19 means that any given year, 10% had a baby, which is a substantial contribution to overall birth rates.
