Income mobility, or the ability of a family or other group to change its economic status, is the subject of a recent report by two Harvard economists.

The pair studied counties all over the United States and found that Maricopa County is basically average for income mobility for children in low-income families, better than 48 percent of other counties.

We talked with Dan Anderson, director of Institutional Research for the Arizona Board of Regents and a former economist for the Department of Economic Security. He said there are a number of factors that would separate the income mobility for someone who lives in Maricopa County from, for example, a resident of Pinal County.
