A recent federal report on American childbearing was literally bursting with records.
But it may be hard to tell the good news from the maybe-not-so-good news.
Media headlines captured the main finding, which was that in 2009 teen births fell to their lowest level since 1940, when the federal government started tracking teen childbearing.
The new birthrate for elder teens, aged 15 to 19, was 39.1 births per 1,000 teens. This marked an amazing 37 percent slide from 1991, the peak year when the birthrate was 61.8 per 1,000 teens.
Declines were seen in teens of all ages, but perhaps the most welcome news was that the birthrate for the youngest girls, aged 10 to 14, was the lowest ever recorded (0.5 births per 1,000).
Lowering teen births has long been a national goal, primarily because most of these births occur to unmarried teens and having a baby at such a young age virtually guarantees a more complicated life for everyone. So these new, lower teen birth numbers are likely to be heartening to most people.
• America’s crude birth rate (13.5 births per year per 1,000 total population) is the lowest ever recorded.
• America’s general fertility rate (66.7 births per year per 1,000 women aged 15-44) declined 3 percent, erasing gains made from 2006 to 2008.
• The total fertility rate fell 4 percent in one year, to 2,007.5 births per 1,000 women in their lifetimes. This was the largest decline in this vital statistic since 1973. It also marked the second year in a row that America’s fertility rate was “below replacement,” i.e., below 2.1 births per woman.
Then when researchers looked at which groups of women were — and weren’t — having babies, more changes emerged:
• The birthrate for young women aged 20 to 24 fell 7 percent, the largest decline for this group since 1973.
• The number of births to women in their late 20s also fell, by 4 percent. So did births to women in their 30s, albeit modestly.
• The only age group to have a higher birthrate was women aged 40 to 44. Their rate of 10.1 births per 1,000 was the highest since 1967.
As for unmarried women and childbearing, there were mixed outcomes.
