The Centers for Disease Control and Prevention (CDC) recently released its annual statistical overview of births in America. The agency reported that total U.S. births plummeted to a 32-year “record low” in 2018—particularly for teenagers and women in their twenties. But though 2018 may have set a new record, other recent years relay much the same story: total births and the general fertility rate (births per 1,000 reproductive-age women) have been falling steadily for well over a decade.
