When individuals disperse from one local group to another, they often do so in the company of relatives. This is known as “kin‐structured migration,” and its effect on genetic population structure is investigated here. It is shown that when migration is kin‐structured, the ratio of between‐ to within‐group variance is increased by a quantity that can be estimated either from behavioral or genetic data. Theoretical results indicate that kin‐structured migration should be most important in populations with high mobility, and analysis of data for humans and lions suggests the kin‐structured migration may have a substantial effect on genetic population structure in both species. Its effect seems to be small in a population of pine voles.
