This link, entitled The Changing Shape of American Cities, gives comparison maps for multi-demographic data points between 1990 and 2012 for dozens of cities, including Columbus. It gives this demographic information by breaking it down by the status at the mile distance from “City Hall”, or from the center of each city’s downtown area.
Using these graphs, here are some examples of the information we can see for Columbus’s immediate downtown.
% of Population with a Bachelor’s Degree at Mile 0
% of Population Aged 22-34 at Mile 0
% of Population Living Below the Poverty Line at Mile 0
Check out these and lots more.
