Eurostat

The datasets are composed by baseline population projections and the following sensitivity tests: •           Lower fertility; •           Lower mortality; •           Higher migration; •           Lower migration; •           No migration. For each of them, data is available as follows: •           Projected population on 1 January by age and sex, and by single year time interval; •           Assumptions on future age-specific fertility rates, age-specific mortality rates and international net migration levels (including statistical adjustment); •           Corresponding approximated values of the life expectancy by age and sex. Moreover, for the baseline projections, the following demographic balances and indicators are available: •           Total numbers of the projected live births and deaths; •           Projected population structure indicators: proportions of broad age groups in total population, age dependency ratios and median age of the population. The time horizon covered is: •           From 2015 to 2081 for the projected population; and •           From 2015 to 2080 for the assumptions dataset.

Live births are the births of children that showed any sign of life. The crude birth rate is the ratio of the number of live births during the year to the average population in that year. The value is expressed per 1 000 persons.

The Fertility data at national level are based on the annual demographic data collection in the field of demography carried out by Eurostat. The completeness of information depends on the availability of data reported by the National Statistical Institutes. The first demographic data collection of each year (T), named Rapid, is carried out in April-May (deadline 15 May of year T); during this data collection the first results on the main demographic developments in the previous year and the population on 1 January of the current year are collected from the national statistical institutes. The Joint demographic data collection is carried out in cooperation with United Nation Statistical Division (UNSD) in the summer of each year, having the deadline 15 September. During this data collection Eurostat collects from the national statistical institutes detailed data by sex, age and other characteristics for the demographic events (births, deaths, marriages and divorces) of the previous year and the population on 1 January of the current and previous years. The Nowcast demographic data collection is carried out in October-November (deadline 15 November of year T). The monthly time series on births, deaths, immigrants and emigrants available from the beginning of current year T are collected, with the purpose of producing a forecast on 1 January population of the following year (T+1). More specifically, during year T the following data are collected and disseminated on fertility field: - Total live births in year (T-1) - Live births by month in year T - Live births by mother's age, year of birth and legal marital status in year T-1 - Live births by mother's age, year of birth and birth order in year T-1 - Live births by mother's age and educational attainment (ISCED 1997) in year T-1 - Declared legal abortions by age in year T-1 Based on this information, Eurostat computes and disseminates the following fertility indicators: Total fertility rate, Fertility rates by mother's age (Age specific fertility rates) and Mean age of women at childbirth. The most recent (aggregated) data on live births can be found under the 'Total population and demographic events - Annual balance (demo_gen)'. This includes also the most recent Eurostat now casts on the demographic indicators (published in December of each year). In principle, the demographic balance is updated three times per year, after each of the national data collections. Detailed information on fertility (by age, sex and marital status, birth order, educational attainment) can be found under the section Fertility (demo_fer). This disaggregated information are updated towards the end of each year based on information collected during the Joint data collection. Moreover, any update sent by the countries in-between data collections are validated, processed and uploaded into Eurostat's demographic database and in Eurostat's free dissemination online database as soon as possible. Aggregates are recalculated accordingly. The data transmitted by the National Statistical Institutes are validated by Eurostat, processed and uploaded into Eurostat's Demographic Database and in Eurostat's free dissemination online database. The data are also disseminated in several thematic and horizontal Eurostat's publications. Data are presented by single country and for aggregates of countries. For EU and Euro Area, only the current and the previous version of the aggregates are published. The currently disseminated aggregates are: EU-27, EU-25, EA-16, and EA-15. Moreover, data is disseminated for the European Economic Area (EEA) and the European Free Trade Association (EFTA).
