Weekly / January 5, 2024 / 72(5253);1394
* Per 100,000 births.
† Triplet and higher-order multiple births are births in triplet, quadruplet, quintuplet, and higher-order deliveries.
The triplet and higher-order multiple birth rate declined from an all-time high of 193.5 per 100,000 total births in 1998 to 78.9 in 2022. From 1998 to 2022, triplet and higher-order birth rates increased among mothers aged <20 years (from 17.6 to 27.5) but declined among mothers aged ≥20 years. In both 1998 and 2022, triplet and higher-order multiple birth rates were lowest among mothers aged <20 years and highest among mothers aged ≥40 years (517.6 in 1998 and 179.0 in 2022) but differences across the age groups narrowed from 1998 to 2022.
