Looking at my part of Brooklyn and the areas around it the lack of affordable housing seems to predictably follow the lines of desirable neighborhoods (like Park Slope), and the addition of transportation into the equation makes little difference since most parts of the area are well served by public transportation. What’s interesting on the map to me is the blue areas (people who are paying more than 30% of their income for housing) are predictably in expensive neighborhoods, with giant yellow patches in less desirable places like Bushwick and East New York, there’s also giant blue patches in Marine Park and Bay Ridge/ Bensonhurst, I don’t know enough about these areas to say why, my guess is that more people there own houses and have to pay property taxes/ deal with foreclosures, etc.
What I’d like to see however is a neighborhood affordability index that took into account more factors about the neighborhood as a whole. The Median Household Income for New York City is listed as $41,053. Of course it’s impossible to live in these more expensive hoods on that income, the people who live there make well in the 100 thousands and above, which means there’s some pretty low incomes in those more affordable hoods drive the median down. While housing prices might change, I’d like to see a study of prices of the rest of costs of living by neighborhood and how much that changes. I think I could predict the results. Moral of the story: it’s effing expensive to live here, and “affordable” housing probably only exists if you have a rent stabilized apartment.
