Where it is not possible to determine migration directly, the indirect measurement of migration¹ involves estimates obtained by the residual² method, in which the change in population between two dates is compared with the change due to natural growth and the difference between the two figures attributed to migration. The vital statistics technique³ consists of computing the difference between total population change and natural increase (701-7). In the survival ratio technique⁴ the death rates of the inter-censal period are applied to age (326-5) the census population and to give the expected population at the end of the period. A comparison between the observed and the expected population may be used to estimate the balance of migration by age. If it were possible to obtain data on either net or gross migration and on the mean population of the area concerned, migration rates⁵ showing the incidence of migration could be computed. In practice, however, it is extremely difficult to specify the population at risk and such rates are therefore rarely used.
