This database (GDIM) contains estimates of absolute and relative intergenerational mobility (IGM) by 10-year cohorts, where individuals born in the 10-year range of cohorts between 1940 and 1989 are estimated. For example, the generation born between 1980 and 1989 are referred to as the 1980s cohort, and parents refer to the parents of the generation of individuals of this cohort. These IGM measures are also available by the type (subpopulation) of parental educational attainment (Mothers/Fathers/Average/Max) and the type (subpopulation) of child’s educational attainment (Sons/Daughters/All, individuals of the surveys). This allows us, for instance, to explore the relationship of mother to daughter IGM.
The GDIM is part of the exercise to generate and compile the IGM estimates which are illustrated and analyzed in the World Bank report titled, “Fair Progress? : Economic Mobility across Generations around the World.” The GDIM description document details how the different estimates are exactly measured, that are featuring in the report.
The GDIM not only includes educational IGM, but also income IGM which are partly generated from the surveys used to estimate the educational IGM which also has wage or earnings data, and partly pooled with the income IGM estimates from other available sources in the literature. GDIM has income mobility estimates for around 70 economies. The report examines the relationship between the key elements of economic mobility – educational and income mobility.
