(Newser) – The number of twins has surged in the past 30 years, according to a new government study. The twin birth rate went from 189 out of 10,000 births (or 1 out of 53) in 1980 to 333 out of 10,000 births (or 1 out of 30) in 2009—a spike of 76%, reports MSNBC's Vitals blog. What's behind it? Experts point to an increased use of infertility treatments and to the growing number of women giving birth at a later age.

The study's lead author says it's not necessarily good news: “It’s really important to note that outcome for twins is much less positive than for singleton pregnancies."

Having more twins will be a survival advantage that will help us replenish our population in the post-apocalyptic hell-scape.

And those fucking annoying selfish 5 foot wide strollers have also increased, 1000 percent. What is it with these idiot parents that they think its perfectly OK to push a huge, doublewide stroller thru a store, or crowds of people, just so little Jason and Sarah dont have to feel like one is less than the other by having to sit behind the other. Or, is it just the new yuppie obsession that begs 'PLEASE notice me, PLEASE, because we are special" *done spewing hate*

I wonder how may of these twins were due to some process to help women get pregnant. Sounds like a man made issue and nothing natural. If it is natural, could it be from all the chemicals we now unknowingly ingest?
