Connecticut’s Luke Foreman Staples High School in Westport has tied the Guinness World Record for having the most sets of twins in a grade at 16. But they may not hold that title for long, as another Connecticut high school in Greenwich is close behind, CNN reports.
Nationwide, one in every 30 children is a twin. In Connecticut, it’s one in every 20, according to a recent National Center for Health Statistics report. The number of twin births has doubled in Connecticut over the last three decades, while, in most other states, twin births increased by closer to 50 percent.
The report links this increase to the increasingly older age of mothers and the increased use of infertility treatments. In Connecticut, state law requires insurance companies to cover in vitro fertilization up to age 40 years old.
