"This paper describes a new method for indirectly estimating age schedules of net migration. The method is illustrated with historical data for the United States. The analysis employs a recently developed technique--iterative intracohort interpolation--to estimate age schedules of net migration from pairs of enumerations of the foreign born by age. The data required for this application are enumerations of the foreign born (or more generally of those born outside the enumeration area) by age in two successive censuses, a life table presumed to reflect the mortality experience of the foreign born during the intercensal period, and, optionally, data on variations in the overall level of migration during the intercensal period. The procedure provides estimates of the average annual number of foreign born net migrants during a decade by their age at the time of entry/exit." (SUMMARY IN ITA AND FRE)
