FEB 10, 2014 –The US Census is always a little behind the times – it takes a while to count people and publish surveys, and in a place like San Francisco, demographic data can swing wildly in just a year or two. So the most recent survey of households, which covers 2007-2011, doesn’t tell even a fraction of the story about how this city is changing.
The tech boom and the eviction epidemic is only a couple of years old, really – at least, that’s when the worst of it’s been happening. (You could almost link the assault on affordable housing in the city to the time of the Twitter tax break. Hmmm.)
Still, the out-of-date data shows some patterns emerging, and it’s fascinating to play around with the map and watch how the low-income population of the city is getting displaced before our eyes.
For example, between 2007 and 2011, 1,148 people with incomes between $35,000 a year and $49,999 a year moved from San Francisco to Alameda County. There were 395 moving to Contra Costa. At the same time, 352 people moved from Alameda to San Francisco.
So the outmigration of middle-class people just to Alameda is about 3-1. (more after the break)
