Hotpads infomap

Hotpads.com is a real estate website that displays home for sale and apartments for rent. Besides listing the properties on an interactive map, Hotpads also lays out data on top of the map that relates to housing. The data they display are Population Density, Per Capital Income, Household Income, Median Age, Percent Renters, Median Rent, and Foreclosures per Capita. The data is available at different granularity (states, counties, districts) and switches automatically at different zoom levels. I've played around with it and found some trends, but I think more can be taken out of this tool.


This shows the median age in different parts of the western U.S. As you can see, most of the coast and borders are young while there is a strip of old people slightly inland (what is that about?). The midwest is significantly older than the southwest, and the colors don't transition as smoothly as one would expect.


This shows the income per capita in different districts of the Bay Area. As you can see, most of the Bay Area is very wealthy expect for pockets of poverty in San Jose, San Francisco, Oakland, and Richmond. It seems like higher the population density, the more likely a disparity in wealth. Same trends can be seen in the New York Area too.

Anyone else find any other insights?
