New Maps Show Racial Segregation in Vivid Color - 2 views

    Looks a lot like GIS to me. But what's this? Not using a broad tract system to generate region averages, but instead more detailed and neighborhood specific system?
    These maps only show racial segregation, but its a promising basis for the improvements for which Davidson advocates in EJ analysis.
    Here's Portland's map:

    This is an important and significant perspective. Compared to other cities, we're not working with a lot when we talk about diversity and segregation in regards to environmental justice. Comparing our EJ mapping to EJ mapping in cities with much more significant segregation would be interesting! (Who wants to do some more GIS mapping for fun over fall break??)
    This ( is Bill Rankin's website, the cartographer who first produced one of these detailed maps in 2009 and inspired Eric Fischer to produce all the others (found here: Check out the downloadable files on Rankin's website (there's one for race and one for income); he includes includes a traditional GIS map of the same data for comparison. (I recommend saving them to your computer and viewing them at a smaller scale to see the patterns more easily.)

    This is from his website:
    "There are indeed areas where changes take place at very precise boundaries... But transitions also take place through gradients and gaps as well, especially in the northwest and southeast. Using graphic conventions which allow these other possibilities to appear takes much more data, and requires more nuance in the way we talk about urban geography, but a cartography without boundaries can also make simplistic policy or urban design more difficult - in a good way."
