Population Mobility and Income Inequality in California
Mary C. Daly, Deborah Reed, and Heather N. Royer

May 2001

Examines trends in family income inequality through 1999, focusing in particular on the relationship between inequality and population movement into and out of California. Finds that international immigration explains about one-third of California's growing inequality over the past three decades, while the substantial exodus from the state in the 1990s had little effect, since out-migrants tended to be in families at all levels of the income distribution.
