Data: Fertility of American Women: 2010

In 2010, the women's education level made less of a difference in their total number of children than it did in 2000. Women 35 to 44 (corresponding with the 25 to 34 age group in 2000) with at least a bachelor's degree had 1.7 births, while women who had less than a high school education had 2.5 births. Eighty-eight percent of women 35 to 44 with less than a high school education had a birth compared with 76 percent of women with at least a bachelor's degree

Other highlights from the press release:

• Foreign-born women were more likely to have ever had a baby than were native-born women by the age of 40 to 44, at 87 percent compared with 80 percent.
• More than half (55 percent) of women who had a child in the last year were in the labor force. Of those women, about one third (34 percent) were working full time, 14 percent were working part time, and 7 percent were unemployed.
• Almost one-quarter (23 percent) of women with a birth in the last year reported living in households with family incomes of at least $75,000. At the other end of the income scale, about one in five (21 percent) were living in families with incomes under $20,000.
• By age 40 to 44, white non-Hispanic women (20.6 percent) were more likely to be childless than Hispanic women (12.4 percent), black women (17.2 percent) and Asian women (15.9 percent). Black women were also more likely to be childless than Hispanic women. Asian women did not differ from black or Hispanic women.
• Differences in childlessness by race and origin are more substantial for women who have never married. Among these women age 40 to 44, white non-Hispanic women were more likely to be childless (69.5 percent) than black women (27.8 percent) and Hispanic women (36.4 percent). No significant difference in childlessness among those who had never married was found between black and Hispanic women, or white non-Hispanic women and Asian women (65.8 percent).
