We examined whether the Gautreaux residential mobility program, which moved poor black volunteer families who were living in inner-city Chicago into more-affluent and integrated neighborhoods, produced long-run improvements in the neighborhood environments of the participants. We found that although all the participants moved in the 6 to 22 years since their initial placements, they continued to reside in neighborhoods with income levels that matched those of their placement neighborhoods. Families who were placed in higher-income, mostly white neighborhoods were currently living in the most-affluent neighborhoods. Families who were placed in lower-crime and suburban locations were most likely to reside in low-crime neighborhoods years later.
