In 2010 it was just over 15% of all (non-Hispanic) black births. By 2015, the most recent complete data available, it was 8.6%.
There are several reasons this could be the case. It could be people leaving high-crime urban areas, which are where the bulk of black teen pregnancy is concentrated. It could be part of the increase in older, more educated foreign-born and second-generation non-Hispanic black immigrant mothers making up a bigger share of black births. It could be both, or some other factors. It’s not an increase in abortions, though.
For perspective, here’s a chart with rough estimates since 1970 and percent changes.
|% teen pregnancy||% change|
The 1970s were pretty bad, as were the 1980s, but the last decade has seen a significant and major turnaround in teen pregnancy. Teen pregnancy for black Americans specifically is particularly “bad” because it’s skewed unmarried for much longer than was the case with white teen pregnancies, starting with under 15 pregnancies being mostly unmarried ones in the 1950s when that wasn’t the case with white pregnancies under 15. In 1966, not long after the famous Moynihan Report, black teen pregnancies to mothers aged 15-19 crossed 50% unmarried.
Through the 1960s and 1970s, teen pregnancy became completely decoupled from marriage for black teen mothers and heavily decoupled for black mothers in their early 20s, culminating in 1978. Five years after Roe V. Wade, black births to mothers in their early 20s were now majority unwed and teen births were 80-97% unwed, depending on age. However, teen births were only about 25% of total births, during the 1960s. The table shows how things shifted after the collapse in married black motherhood during the 1970s and 1980s.
All birth data used for rough percentages comes from Monthly Vital Statistics Reports or National Vital Statistics Reports.
