Experts said several factors may be combining to drive the declines, including shifting attitudes about motherhood and changing immigration patterns. The provisional report, based on a review of more than 99 percent of the birth certificates filed nationwide, counted 3.853 million births last year. That’s the lowest tally since 1987.
Newborn babies fill the nursery of a postpartum recovery center in upstate New York, Feb. 16, 2017. According to a Centers for Disease Control and Prevention report released May 17, 2018, 2017 saw the lowest number of U.S. births in 30 years.
Births have been declining since 2014, but 2017 saw the greatest year-to-year drop, about 92,000 less than the previous year. That was surprising, because baby booms often parallel economic booms, and last year was a period of low unemployment and a growing economy.
What's causing this?
But other factors are likely at play, experts said. One may be shifting attitudes about motherhood among millennials, who are in their prime child-bearing years right now. They may be more inclined to put off child-bearing or have fewer children, researchers said.
Another may be changes in the immigrant population, who generate nearly a quarter of the babies born in the U.S. each year. For example, Asians are making up a larger proportion of immigrants, and they have typically had fewer children than other immigrant groups. Also, use of IUDs and other long-acting forms of contraception has been increasing.
