Description
Rates of multiple births at state and county levels
The rate of twin births in the US has been increasing since 1980, reaching a high if 33.9/1,000 in 2014. The rate of higher order multiple births rose sharply until the late 1990s and has trended downward since then. Increased rates of multiple births have been associated with the use of fertility therapies, and the decrease in higher order multiple births have been linked to changes in these procedures. Multiple birth pregnancies and deliveries are higher risk for adverse outcomes for both mother and infants.
