Self-selection mechanisms are important because they shed light on what has been relevant to those who migrate, especially in the nineteenth century. Using new micro data gathered from emigrant permit lists and census data in the homeland, I compare over 10,000 German emigrants to those who stayed at home. I find that artisans were over-represented and farmers and labourers both under-represented. The emigrant population was positively self-selected in terms of skills, but negatively self-selected in terms of financial wealth.
