With more Americans living alone and significant transportation costs for middle-class Americans, where do the carless Chicagoans tend to cluster?

So where do those carless Chicagoans live, and how many of them are there? A lot, it turns out. If you break down Chicago by cars and household size using 2012 census numbers, these are the only groups of more than 100,000:

One person, one vehicle	193,174
One person, no vehicle	168,004
Two people, one vehicle	135,143

Along the northern lakefront, around half the households don’t have a car; there are pockets in the Near North Side and Lake View over 60 percent. In one Edgewater tract, it’s over 70 percent. It’s not the highest percentage, though—there are two tracts in one of the poorest stretches of the South Side, between U.S. Cellular Field and 47th Street along the Dan Ryan, above 80 percent.

As you move north and west and the city gets less dense, the percentage of carless households drops off. There’s an exception, though: one tract in Logan Square, adjacent to the California Blue Line stop, where 41 percent of households don’t own a car. The “twin towers” transit-oriented development that’s going up at 2293 N. Milwaukee, and causing controversy as it goes, will live right next to that tract.

If I had to guess, this is related to income, age, more expensive parking options (for example, having to pay for a garage spot as opposed to plenty of street parking), and housing types (single-family homes which are more attractive to families versus apartments, condos, etc.). How well would these clusters line up with where the Creative Class lives?

The headline suggests that this is has led developers to respond with what they are proposing and building. Yet, the article doesn’t say much regarding these changes. For example, how about more shared streets like have been proposed for a few spots in Chicago? How about more bike lanes in these areas? How about more high-rise housing? If these population clusters hold and developers are indeed responding, these could be very unique places in a few decades.
