Data are collected by Eurostat using the recommended definition of 'usually resident population'. Data represent the number of inhabitants of a given area on 1 January of the year in question (or, in some cases, on 31st December of the previous year). Population numbers are either based on data from the most recent census or on population registers.
Eurostat defines usual residence as the place where a person normally spends the daily period of rest, regardless of temporary absences for purposes of recreation, holidays, visits to friends and relatives, business, medical treatment or religious pilgrimage. The following persons alone are considered to be usually residents of the geographical area in question:
- those who have lived in their place of usual residence for a continuous period of at least 12 months before the reference time; or
- those who arrived in their place of usual residence during the 12 months before the reference time with the intention of staying there for at least one year.
Net migration plus statistical adjustment
Net migration is the difference between the number of immigrants and the number of emigrants. In the context of the annual demographic balance however, Eurostat produces net migration figures by taking the difference between total population change and natural change; this concept is referred to as net migration plus statistical adjustment. The statistics on 'net migration plus statistical adjustment' are therefore affected by all the statistical inaccuracies in the two components of this equation, especially population change. From one country to another 'net migration p statistical adjustment' may cover, besides the difference between inward and outward migration, other changes observed in the population figures between 1 January in two consecutive years which cannot be attributed to births, deaths, immigration and emigration.
