Roughly one million Swedes emigrated to the USA between 1870 and 1920. These emigrants gave rise to over four million individuals with a Swedish ancestry currently living in the USA. This study shows that Swedes have maintained the geographic concentrations chosen by their parents and grandparents. Also, Swedish migrants were on average less educated than the US-born white population, yet their descendants tended to be relatively better educated. The statistical analysis of the data shows that Swedish-born men had lower, and women much lower, earnings than the native born. However, this position was not carried over to the subsequent generations who performed similar to natives with similar characteristics.
