We received an interesting press release from the RentCafe service based on a study they've done about which zip codes have the most renters, and which are growing fastest.

Of the 41,692 zip codes in the United States, the 60608 zip code, which covers the north half of Chicago's McKinley Park neighborhood, ranked 273rd for the most renters, with 54.6 percent of residents renting, versus owning their homes. The study also listed the 60609 zip code, which mostly lies south of 35th Street in McKinley Park, ranked 243rd, with 57.8 percent of residents who are renters.

Neither of McKinley Park's zip codes were noted as areas with the fastest-growing renter populations, or zip codes where renters have recently switched to outnumbering owners.

However, Chicago was noted as one of the metro areas where this is happening in general, and a number of Chicago-area zip codes made these lists.
