The advent of molecular genetics has brought invaluable information, which is now routinely used by anthropologists in their attempt to reconstruct our demographic past. Since mitochondrial DNA loci are much more similar between populations than are Y‐chromosome loci, it is suggested that women had a much higher migration rate than men throughout history. Based on an examination of intergenerational migration patterns in three large demographic databases, we bring this inference into question. In some early Canadian settlements (St. Lawrence Valley and Saguenay), and in the former Krummhörn region of northwest Germany, men whose fathers were migrants were more likely to migrate, while the migration probability of women was largely independent of that of their mothers. As a result, men's movements were less effective in preventing genetic differentiation between populations than women's movements. In order to account for the impact of transmission, we propose a slight modification of Wright's island model. We also address the relevance of this model at the regional scale, and we discuss the supporting historical and anthropological literature. We conclude that the widespread patrilocal rules of postmarital residence have generated both a higher female migration rate and a patrilineal dependency in the propensity to migrate.
