I don't think this shows the entire picture. The USA has larger disparaties across quintiles, in large parts due to its history as a country of (sometimes involuntary) immigrants. I think it will be interesting to see how Sweden's favorable metrics here change as a result of their wave of unskilled immigration, which is probably too recent to be fully incoporated in any generational study. I'd also be interested to see mobility in 'absolute' terms, perhaps relative to global percentiles. Moving up 10% in a very disparate country might reflect more social motion than jumping two quintiles in a very flat country. Also, moving between income quintiles misses other aspects that might be relevant for a broader definition of social mobility: moving into the top 1% or top 0.1% of income and any movement in wealth. I'm not having luck finding a source at this moment, but I recall seeing that the USA performs favorably on this metric compared to europeans with millenial legacies of state-sanctioned hereditary nobility.
