PO0213: COMPONENTS OF CHANGE IN POPULATION FIGURE BY COUNTY
As of 1 January 2016, Statistics Estonia uses a new source of residence data and methodology for calculating the population figure, which have to be taken into account upon analysing changes. The place of residence is the place of residence stated in the Population Register, if it is left unmarked, the persons will be categorised under ''County unknown''. More information can be found under Definitions and Methodology.
Up to 2014 (incl.), can be regarded as unregistered external migration; 2015 – the difference due to the methodological change and transition from the place of residence recorded in the census to the place of residence recorded in the Population Register.
