What do you know about twins, triplets or quads?
Are you seeing double (or triple) every time you go to the grocery store or the shopping mall? You are--twins, triplets, and even quadruplets are much more common these days than just a decade ago. In the US, the number of twin births has risen by 67% and the number of triplet and higher order births by 548% since 1980. Although triplets and higher-order multiples are increasing at a faster rate, twins account for more than 93% of all multiple births each year. One-fourth of this increase is attributed to delaying childbearing and the naturally higher occurrence of multiple births to older mothers, but the majority is the result of fertility-enhancing agents and assisted reproductive technologies.
- Half of all multiple births today are to women ages 30 and older, twice as many as in 1980.
- Three times as many women ages 35 and older, and four times as many women ages 40 and older are having twins today compared to 1980.
- Five times as many women ages 35 and older, and ten times as many women ages 40 and older are having triplets or quadruplets today compared to 1980.
