An eighty five puts Rogers Park in the top fifty neighborhoods (number 48) of Chicago out of over two hundred. The transit score is 75 (surprising given the number of Metra and L stops) and the bike score is a 71 (this will increase with the new bike lane on Clark). Walkscore.com has compiled an exhaustive live of nabes in Chicago from big to little. Ever heard of Tally's Corner at 215 (last place)? Me neither.
Given that the city is cut up into that many different areas Rogers Park has a solid score taken as a whole neighborhood. Chicago gets a sixth place in large cities with an overall average of 74.8. So Rogers Park is above average scoring a solid B. The site proclaims "Most errands can be accomplished on foot in Rogers Park."
The map above is almost completely green because of so many Walker's Paradises (like 1523 w Lunt a 94). Areas in light yellow score lower east of Sheridan (1209 w Sherwin gets 75 very walkable) and near Ridge Road (2024 w Lunt gets 69 somewhat walkable). The score is largely based on how many and which businesses are in walking distance. In dense neighborhoods with large populations over 40k Rogers Park is only beat out by Lake View with a score of 90.
