Martha Bailey and team released LIFE-M, a longitudinal, intergenerational family electronic micro-database
The LIFE-M project combines millions of U.S. vital records (birth, marriage, death certificates) with census information into a longitudinal and intergenerational micro-database. With the help of cutting-edge, machine learning techniques, the LIFE-M data follow four generations of Americans from birth to death. High quality training data is used to achieve large-scale performance at high rates of precision. Birth cohorts begin in late 1800s and include their great grandchildren born between 1915 and 1975. There is almost no work on these data, so ideal to use for a dissertation.
The data can be downloaded from OPEN ICPSR here.
