More American women are choosing not to have children than three decades ago, according to a new report. Nearly 20 percent of older women do not have children, compared to 10 percent in the 1970s, the Pew Research Center said. ... Education also is a factor in a woman's choice to be a mother. The more educated women are, the higher the childless rate is.
