Definition

Usually resident population in April of the reported year, as estimated by the Central Statistics Office of Ireland from the census, births, deaths and migration. Estimates are published in thousands, rounded to the nearest hundred persons.

Ireland only: country, the eight NUTS 3 regions and the 26 counties. The reference month differs from the 1 January population in population, so the two are separate series.
