Behold the results of the SF hoodie survey!
Based on the 500+ people who responded, it looks like San Franciscans (at least those who read blogs) own approximately 4 hoodies per person (though there’s a long tail of many SFians more than 10.) The Outerlands lay claim to hoodie per capita, seemingly out of thermal necessity. Using Nate Silver precision, we can extrapolate and jump to the conclusion there are over 3 million hoodies in San Francisco, making it the predominate life form in our city.
Of course, this poll was heavily weighted towards the Mission.
