Mapping the Great Housing Divide in New York and San Francisco

It’s no secret that New York and San Francisco face a staggering crisis of housing affordability. But not all neighborhoods in these cities have seen their housing prices and rents climb. In fact, each of them is beset with considerable housing divides, which mirror and reinforce their broader economic gulfs. While many neighborhoods have seen median home sale prices increase, gentrification has not spread throughout these cities across the board. Many others have seen sale prices stagnate and, in some cases, even decline.

These housing divides can be seen in a series of maps from Property Shark, an online site that tracks housing sale prices in cities, which show the changes in sale prices across neighborhoods in both San Francisco and New York from 2004 to 2014. The data in these maps track the change in median sales price of residential housing on a per square foot basis.
