Index of migration effectiveness  (INDEX of migration effectiveness)


The generic term migration rate 1 refers to any rate which measures the relative frequency of migration within a population. Unless indicated otherwise these rates should be taken as annual migration rates 2. They may be obtained as the ratio of the average annual number of movements during a certain period, to the average population of the period. An annual rate of net migration 3 and an annual rate of total migration 4 are calculated in a similar fashion by using the appropriate information on net and total migration. An index of migration effectiveness 5 or effectiveness index 5 is calculated as the ratio of net migration to total in- and out-migration. The range of the index is from zero, when arrivals and departures are equal in number, to one, when migration is entirely one way.

  • 2. Other denominators may serve to compute the rate, such as the population at the beginning or the end of the period, or the number of person-years lived by the population of the area.
  • 5. Also: Index of migration efficiency or efficiency index.
