The data in this section cover population and population change (migrations, births, deaths) as well as infant mortality data.
Data are presented country by country and for groups of countries in the European Union (EU-27) and the Economic and Monetary Union.
Total Population is the average population during the year. It is available by sex and five-year age groups.
According to the United Nations (UN) definition, a death is the permanent disappearance of all evidence of life at any time after live birth has taken place (postnatal cessation of vital functions without capacity of resuscitation). This definition therefore excludes foetal deaths.
Most countries measure mortality both by age completed (age last birthday) and age reached during the year. Only Cyprus, and Malta measure mortality by age completed only. Mortality rates by age have been recalculated by Eurostat to the same definition, the age reached during the year of the event. This permits rates to be recombined by generation.
The infant mortality rate represents the ratio between deaths of children under one year and the number of live births in a given year. Countries, however, use different definitions for spontaneous abortion, early foetal death and late foetal death (or stillbirth). A stillbirth for example is, generally speaking, the product of a birth that shows no signs of life during and after the whole process of being born. But countries require different lengths of pregnancy to distinguish between early and late foetal deaths (ranging from 21 to 28 weeks). Some countries even require a certain minimum length (varying between 25 and 35 centimetres), some a certain minimum weight (500 or 1000 grams). Differences of definition lead to variations in the measurement of perinatal mortality.
Data are collected by Eurostat from the National Statistical Offices. National annual estimates of population are based either on the most recent census round, applying the component method, or on the data extracted from a population register.
Provisional and estimated data are revised on a continuous base according to the most recent updated data provided by the countries.
