Reduced access to infertility treatments early in the pandemic may have contributed to a drop in twin births, data from the U.S. Centers for Disease Control and Prevention (CDC) suggest.

The number of twin births fell 7 percent between 2019 and 2020—from 120,291 to 112,437—compared to an average 2 percent-per-year decline from 2014 to 2019, researchers reported on Wednesday in the CDC’s National Vital Statistics Reports, based on data from 50 states and the District of Columbia.
