Maternal mortality rates in the United States fell in 2022 after at least three years of continuous increases, new federal data shows. In 2022, 817 women in the U.S. died of maternal causes with a rate of 22.3 maternal deaths per 100,000 live births, according to the report published early Thursday by the Centers for Disease Control and Prevention's National Center for Health Statistics. This is a drop from the 1,205 women that died in 2021 with a rate of 32.9 maternal deaths per 100,000 live births.
