Remember that time I was blasting a startup for russian dating website nyc single women from NYC to San Francisco? And about how I had all of this cool data that showed that there were actually more single men in New York, and they were probably just hiding indoors playing video games?

And that other time I showed how I was completely kind of horribly somewhat wrong, and that Manhattan is nothing but an island-nation of nothing but women? Now it’s time to take a look at the other half of the puzzle: the ratio of single men to single women in the San Francisco Bay Area. Note: This is all fiercely heteronormative, and I’m sorry about that, but such is the data bestowed by the US Census Bureau. If you’d like to see a hilarious side effect of this, scroll down to the last image. Census means anyone who isn’t married, so even long-term relationships don’t come into the picture at all. It’s singles by age and zip code in the SF Bay Area.

Use the age range sliders to get it to an area that’s meaningful to you, I’ve started it off at 20-34. Let’s take a closer look at SF proper. Ooookay, that’s a lot of single men. Very much the opposite of what we found about New York, where the core of Manhattan was primarily single women. And yes, this map doesn’t account for sexuality at all, so there are plenty of men in those blue zones with zero interest in women. If we zoom out, things even out a bit.
