More U.S. women having twins; rate at 1 in 30 babies

The number of twins born in the U.S. soared over the last three decades, mostly the result of test-tube babies and women waiting to have children until their 30s, when the chances of twins increase. In 2009, 1 in every 30 babies born in the U.S. was a twin, an astounding increase over the 1 in 53 rate in 1980, according to a government report issued Wednesday.
