An anonymous reader quotes a report from NPR: The birthrate fell for nearly every group of women of reproductive age in the U.S. in 2017, reflecting a sharp drop that saw the fewest newborns since 1978, according to a new report by the Centers for Disease Control and Prevention. There were 3,853,472 births in the U.S. in 2017 -- "down 2 percent from 2016 and the lowest number in 30 years," the CDC said. The general fertility rate sank to a record low of 60.2 births per 1,000 women between the ages of 15 and 44 -- a 3 percent drop from 2016, the CDC said in its tally of provisional data for the year. The results put the U.S. further away from a viable replacement rate -- the standard for a generation being able to replicate its numbers. "The rate has generally been below replacement since 1971," according to the report from CDC's National Center for Health Statistics. "The decline in the rate from 2016 to 2017 was the largest single-year decline since 2010," the CDC said. The 2017 numbers also represent a 10-year fall from 2007, when the U.S. finally broke its post-World War baby boom record, with more than 4.3 million births.
