According to data from the free dating site OKCupid, which The Boston Globe calls “the Google of online dating,” Portland, Oregon, has the distinction of being America’s sluttiest city.
Amy Rolph writes for the seattlepi, August 19, 2011, that OKCupid arrived at this determination by mapping where site users seeking “causal sex” are located. Those numbers were converted to percentages to determine which cities are the most promiscuous.
Here are the top 10 sluttiest cities in America:
- Portland, Oregon
- Seattle, Washington
- Pittsburgh, Pennsylvania
- Miami, Florida
- San Francisco, Calif.
- Dallas, Texas
- San Bernardino, Calif.
- Denver, Colorado
- San Diego, Calif.
- Houston, Texas


SF is number 5? Man Portland must be really jacked up!
Portland & Sea beat SF? I blame the 345 days of rain we get
I find it hard to believe Atlanta didn’t make the list; this town is Whore Vegas.
But the Portland and Seattle part didn’t surprise me (former Seattle resident here), mostly for the reason DCG mentioned.
