美国年轻女性生育率创新低

The number of babies born to young women continues to decline in the United States.

A record low number of teenagers and women in their 20s gave birth in the U.S. in 2015, according to new government data released Thursday.

Preliminary figures from the Centers for Disease Control and Prevention showed the birth rate among mothers ages 15 to 19 fell by 8 percent last year, and has dropped 64 percent since 1991.

Overall, U.S. mothers gave birth to 3.98 million babies in 2015, only slightly fewer than the year before. The birth rate was 62.5 per 1,000 women.

The numbers continue the trend of women giving birth later in life.

Those age 20 to 24 had 3 percent fewer births last year, a figure that has declined by 27 percent during the past decade. For those 25 to 29, the birth rate fell by 1 percent.

But women in their 30s saw their fifth consecutive year of increases, while the birth rate for women 40 to 44 jumped by 4 percent last year.
