Net immigration  (NET immigration)

The contribution of migration (801-3) to overall population growth or population growth due to migration 1★ (701-1) is due to net migration 2, i.e., the difference between the number of arrivals 3 and the number of departures 4. Net migration can have a negative or a positive sign; net immigration 5 or net in-migration 5 is used when arrivals exceed departures, and net emigration 6 or net out-migration 6 when the opposite is true. The sum of arrivals and departures in a country can be used to measure the volume of migration 7. A similar concept, applied to sub-areas of a country, is the migration turnover 8. The net stream 9 or net interchange 9 of migration between two areas is defined as the difference between the stream (803-9) and the counterstream (803-11), whereas the gross interchange 10 is the sum of stream and counterstream.
