These may be a little off. I did a grad school paper many years ago

on welfare reform.

Notes on teenagers
As the statistics show, teenage mothers comprise a very small part of the welfare population.
And contrary to popular belief, teenage pregnancy has declined in the last several decades. Many are surprised to learn that the height of teenage pregnancy in the U.S. actually occurred in the 1950s - a decade known for its supposed conservative social values. Between 1960 and 1992, the number of births per 1,000 teenagers (aged 15-19) declined from 89 to 61. (2)
