Dr. Daniel T. Lichter is director of the Cornell Population Center and the Ferris Family Professor in policy analysis & management and sociology at Cornell University and a Carsey Senior Fellow. Much of his research has focused on spatial patterns of economic opportunity and inequality, especially in rural communities and regions such as Appalachia and the so-called Black Belt. He also has evaluated the implications of welfare reform and “healthy marriage” initiatives on the family, marriage and cohabitation, and children’s changing living arrangements. His most recent work has examined racial and ethnic boundaries in "new immigrant destinations,” where inter-group relations are often expressed in changing patterns of racial residential segregation and interracial marriage. Dr. Lichter is a former editor of Demography. He also is past-president of the Rural Sociological Society (2010-2011) and the Population Association of America (2012). His PAA presidential address (“Integration or Fragmentation? Racial Diversity and the American Future”) was published in the April 2013 issue of Demography.
