Association between polygenic score and likelihood of migrating out of New Zealand. The value at the end of each arrow is the average standard-deviation difference in polygenic scores (with the standard error of the estimate in parentheses) between Dunedin Study members who moved to that area (North America, n = 14; Europe, n = 41; Asia and Africa, n = 13; Australia, n = 162) and members who remained in or returned to New Zealand. Migrants were defined as Dunedin Study members who had lived and worked abroad for a minimum of 12 months since the age of 21 and who were still living abroad at the age-38 assessment.
