I have never understood how people with median household incomes afford anything in the city. For instance, the image someone else already linked shows even the lowest rents at almost $2k: http://sfist.com/attachments/SFist_Brock/SF-Infographic.png http://sfist.com/attachments/SFist_Brock/SF-Infographic.png Yet the OP shows several downtown stops, like Powell St. and Civic Center as having less than $24k of income. That is, the average income is less than the average annual rent. I have no idea how that possibly works.
