Do you get the feeling that there are more twins around these days than there used to be? No? Well, you should, because according to a new study in the journal Human Reproduction, the "twinning rate" has increased by one-third since the '80s—up from 9 to 12 twins per 1,000 deliveries. Currently that adds up to about 1.6 million twins born each year across the world—meaning one out of every 42 babies is a twin. Helping drive this is the increasing use of medically assisted reproduction, and the delay in childbearing (twinning has been found to increase with a mother's age).
