According to the 2014 US Census, 47.6 per cent of women go through their peak-fertility years (ages 15 to 44) without giving birth.This can only be read as 47.6% of women over 44 don't have children.
A ridiculous claim. So I googled it, betting it was a mangling of some fact by the writer.
The Huffington Post describes what is actually happening:
According to the U.S. Census Bureau’s Current Population Survey, in 2014, 47.6 percent of women between age 15 and 44 had never had children, up from 46.5 percent in 2012. This represents the highest percentage of childless women since the bureau started tracking that data in 1976.And it will drop further after age 34.
Time reported that this pattern is particularly pronounced for women between 25 and 29 — 49.6 percent of women in that age group don’t have kids. Unsurprisingly, after age 30 those numbers drop and more women become moms. The survey found that 28.9 percent of women ages 30-34 are childfree.
From the US census:
2.0 - Average number of children that women age 40 to 44 had given birth to as of 2014, down from 3.1 children in 1976, the year the Census Bureau first began collecting such data. The percentage of women in this age group who had ever given birth was 85 percent in 2014, down from 90 percent in 1976.
So now we have 15% of women go through their peak fertility years (15-44) without giving birth.
Fertility rates may be dropping, but not that fast.
