The Fragile Families Opportunity Insights Data on County Intergenerational Mobility Data Appendage contains county level data on intergenerational mobility and its theorized correlates. County data from Opportunity Insights was merged to the county residence of the focal child’s mother and father at Baseline, Year 1, Year 3, Year 5, and Year 9. All information on counties was obtained from data made publically available by Raj Chetty and Nathaniel Hendren (2017) at Opportunity Insights. Chetty and Hendren used de-identified tax records on more than five million children between 1996 and 2012 to estimate the effect of growing up in each U.S. county on children’s future prospects for upward mobility. In this data appendage, we include Chetty and Hendren’s preferred estimates of causal place effects by county for adult household income, individual income, and probability of marriage. These county measures are also disaggregated by family income (low- and high-income) and child sex (male and female). In addition, the data appendage includes the 48 county level covariates theorized by Chetty and Hendren to be correlated with intergenerational mobility.
