We know that 2014 is the year of the rear in the U.S., but what about the rest of the world? Is the current renaiASSance a global phenomenon, or just an American thing?

The good people over at PornHub, purveyors of fine adult films since 2007, have crunched the numbers to answer a question that has been debated in bars since bars were just caves where cavemen went to avoid their cavewives: boobs or butts?

The answer, according to searches on PornHub and YouPorn, is that butts reign supreme in the U.S., South America and Africa, while boobs are more popular in Europe, Asia and Oceania.

Curiously, the breakdown seems to have something to do with proximity to the equator, with hotter climates preferring butts, and more frigid climates going for boobs. Is this possibly due to some genetically-embedded instinct to motorboat them for warmth? (Hint: no.)

On a more micro level, the United States seems to break down the same way, with all of the states preferring boobs being located in the northern part of the country. 

The adult film scientists over at PornHub Insights also discovered some interesting trends involving other search terms. For instance, the Middle East has a thing for feet, legs are big in Eastern Europe, and those freaks over in southeast Asia are into pregnant women. They get into all kinds of pervy (yet still mostly safe for work) detail over at the PornHub Insight site
