Intergenerational educational mobility reflects a welfare state's ability to provide citizens with opportunities to climb the social ladder. Representing two distinct welfare state types, studies have contrasted mobility patterns in Scandinavia and the United States but have provided no consistent answer as to who achieves the highest level of intergenerational educational mobility. We conduct a meticulous examination of intergenerational educational mobility in Denmark, Norway, Sweden, and the United States for cohorts born between 1958 and 1987 using comparable operationalizations and methods and the best available data (administrative data in Scandinavia and eight surveys in the United States). We focus on methods that capture relative mobility. Across models, we find that inequality in Scandinavia is 20 percent to 30 percent lower than in the United States. A multiverse analysis, which can run a large number of models within a single framework, shows that our results are robust to alternative variable specifications.
