When adequate data on migration are unavailable, demographers infer such data indirectly, usually by turning to residual methods of estimating net migration. This paper sets out and illustrates an inferential method that uses population totals in the first age group of birthplace‐specific counts of residents in each region of a multiregional system to indirectly infer the entire age schedule of directional age‐specific migration flows. Specifically, it uses an estimate of infant migration that is afforded by a count of infants enumerated in a region other than their region of birth to infer all other age‐specific migration flows. Since infants migrate with their parents, the migration propensities of both are correlated, and the general stability of the age profiles of migration schedules then allows the association to be extended to all other age groups.
