That's right—during spring break, Tinder usage on South Padre Island, Texas spikes nearly 2,500 percent. Call it the obvious winner (and, we suppose, loser) here. As of the 2010 census, the island was permanent home to just over 2,800 infinitely patient souls—but it swells to become essentially a small city each March. At its peak, 50,000 students have their run of the place, and from the looks of it, they're all on Tinder.

New Orleans and Miami might post numbers that look pitiful, but that's still up 25 percent, and it's because Tinder usage there is extremely strong throughout the year—and because those cities host what is essentially a year-round spring break. Boulder, meanwhile, gets our vote for Unexpectedly Horniest Place on the Planet.
