The big (genetic) sort? Reassessing migration patterns and their genetic imprint in the UK

This study reassesses findings of Abdel Abdellaoui (2019) that genetically selective migration may lead to persistent and accumulating socioeconomic and health inequalities between types (rich or poor) of places in the UK. Their work categorized migrants who moved to the same type of place (rich-to-rich or poor-to-poor) as non-migrants. We re-investigate the question of genetically selective migration by examining migration patterns between places rather than place-types and find genetic selectively in whether people migrate rather than where. For example, we find evidence of positive selection of people with genetic variants correlated better education moving from rich to poor places with our measure of migration that was obscured in the earlier work that used a non-standard measure of migration. ### Competing Interest Statement The authors have declared no competing interest.
