LOS ANGELES – After a six-month-long survey of random users, a chat site believes it has the answer to an ages-old question: What country can lay claim to the largest number of super-sized bosoms?

According to the folks at DirtyRoulette, American women ran away with the crown. Between October 2015 and March 2016, users worldwide chose U.S. racks by a margin of nearly three to one. American women took 32.2 percent of the vote, followed by Russia’s 13.4 percent. Other countries finished with single digits.

“It is no surprise to see America come out on top,” said Shea Robins, DirtyRoulette’s press director. “American women have always had a reputation for large breasts, but this study now conclusively proves that the U.S. is home to the largest breasts in the world.”

In fact, the whole North American continent earned bragging rights by garnering a total of 37.9 percent of the votes, almost 7 percent more than its closest rival, Europe. Breast sizes in North America, and particularly in the U.S., have been on the increase since 1983, according to Robins, ballooning from an average of 34 B to 34 DD. What’s more, American breasts get bigger every year, she added.

The study also asked users what they consider “ideal breast size.” More than half of respondents answered D-cups or larger. The majority of men said they don’t care whether breasts are natural or augmented.

Launched in 2010, DirtyRoulette bills itself as “chat-roulette for naked people.” The site is free and available in six languages (English, German, Spanish, French, Portuguese and Italian) and mobile-friendly.
