In the name of guiding the single people of the world into fulfilling relationships (which they can then brag sickeningly about on social media) Facebook crunched a bunch of data to guide people on which cities hold the best odds for love.

Memphis came first for most single women for every man, while apparently if you move to Colorado Springs you’ll have more chance of falling into a relationship than any other city in America.
