This map image comes from the Diversity Data web site and shows the child opportunity index for the Chicago region.
The lighter colored areas are neighborhoods where youth have less opportunities than in other places.
These are areas where non-school, volunteer-based tutoring, mentoring and learning organizations are most needed, along with many other poverty reduction solutions.
A nice feature of this site is that you can create a map view of Chicago, Boston or another city, then save it as a jpg, using a feature built into the site. Then you can include the image in a blog like I've done here.
It's another example of how maps can be used to focus attention, and resources, on all of the high-needs areas of a big city like Chicago.
