In an effort to better understand how Americans' mobility outcomes compare with those of their counterparts in other nations, the Pew Economic Mobility Project partnered with the Russell Sage Foundation and the Sutton Trust to commission a multi-country study on economic mobility, "Cross-National Research on Intergenerational Transmission of Advantage" (CRITA). As part of this initiative, researchers in 10 countries investigated how socioeconomic advantage, as measured by parents' education, is transmitted over the course of one's life. Sixteen studies looked at relationships between family background and children's outcomes related to mobility--such as their educational attainment, economic status, and health--at various ages. This approach allows for comparisons across studies of current generations of children, shedding light on how mobility may be influenced in different ways over the life course and in different countries. Key findings from the CRITA initiative include: (1) In the United States, there is a stronger link between parents' education and children's economic, educational, and socio-emotional outcomes than in any other country investigated; (2) Across countries, disparities in children's outcomes by family background occur as early as they can first be measured; (3) Preschool exposure can have lasting positive effects on educational and economic disparities by family background, especially for low- and middle-income children; (4) Disparities in early child outcomes persist into adolescence; and (5) Across countries, policies and institutions do influence mobility.
