(Unfortunately, link to the mobiliy project was not working, hopefully fixed soon)
And, here is the more detail on the story about the importance of geography in determining income mobility. location matters story also from NYT.
In addition to mobility higher in areas where poverty was dispersed, the article summarizes:
mobility was also higher in areas with more two-parent households, better elementary schools and high schools, and more civic engagement, including membership in religious and community groups.
