Generally it is said that good things come in pairs, and new government data shows that the fact seems to be quite true for American babies. Last year, the US twinning rate hit a record with 33.9 out of every 1,000 births that involved twins.
According to a report from the National Center for Health Statistics, though the rise from rate of 33.7 per 1,000 births in 2013 isn’t sufficiently large to be statistically significant, but it has been qualified as ‘a new high for the nation’.
Of all the born twins, 78,788 were delivered by white women, 23,546 were delivered by black women and 22,051 were delivered to Latinas.
Though the twinning rate has set a record last year, the total number of twin births was just the 5th highest on record. In total, 135,336 twins took birth in the US in 2014. The number was 2.3% higher as compared to year 2013, but 2.6% less than the year 2007’s all-time high of 138,961 twin births. The twinning rate was 32.2 per 1,000 births in 2007.
The surge in twin births can be traced to twin trends. Women in America wait for longer time to have babies, and the ones, using in vitro fertilization are being quite conservative with their treatments.
In 2014, the average age of first-time moms kept on increasing and set a new US record at 26.4 years. Altogether last year the birth rate for teen women and the ones in early 20s dropped, whereas a rise was seen in the birth rate for women ages 25 to 44 years.
