A “twin boom” in the ‘90s resulted in a million extra twins born between 1981 and 2012, which means the Millennial generation has more twins than any before them—and apparently that could be a bad thing.

A “twin boom” in the ‘90s resulted in a million extra twins born between 1981 and 2012, which means the Millennial generation has more twins than any before them—and apparently that could be a bad thing.
