It appears Greenwich High School has broken 's Guinness Record for the .
According to a report in the Greenwich Time, the GHS Class of 2015 has 18 sets of twins, thus beating the Westport Staples High School Class of 2014, which was recently listed in the Guinness Book of World Records with 16 sets.
What's more the GHS Freshman Class has two sets of triplets — and its Class of 2012 has a tying 16 sets of twins. Altogether there's currently 62 sets of twins at GHS, according to the report.
Why the preponderance of twins? Women are waiting until they're older to have children — which increases the chance of multiples — and fertility treatments, according to the report. As a result the U.S. twin birthrate is up 76 percent in the past 30 years.
Still, twins account for only 2 percent of the overall U.S. population, according to US Census data. Thus the concentrations of twins at GHS and Staples (where they represent 8.42 percent of the Class of 2014) are remarkable.
