3.1. Data description

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.

3.2. Classification system

The territorial breakdown of the countries is according to the (EU) Regulation No 1260/2013 on European demographic statistics.

3.3. Coverage - sector

Demography.

3.4. Statistical concepts and definitions

Base population on 1 January2015 is the population of the country as reported in the annual demographic statistics data collection run by Eurostat.

Age-specific fertility rate is defined as the ratio between the number of live births occurring to women between ages x and x+1 and the number of person-years lived by women between ages x and x+1, over one calendar year.

Age-specific mortality rate is defined as the ratio between the number of deaths between ages x and x+1 and the number of person-years lived in the age interval x and x+1, over one calendar year.

Life expectancy at age x is the average number of additional years of life that a survivor to age x will live beyond the age x, if subjected to the assumed mortality conditions.

Median age is defined as the age 'x' such that exactly one half of the population is older than 'x' and the other half is younger than 'x'.

Proportion of population in each of the main demographic age groups is the number of - respectively - children (0–14 years), persons in working-age (15–64 years), elderly (65 years and over) and oldest-old persons (80 years and over) in the total population.

Young-age-dependency ratio is defined as the ratio between the number of persons aged 0-14 over the number of working-age persons (15-64 years).

Old-age-dependency ratio is defined as the ratio between the number of persons aged 65 and more over the number of working-age persons (15-64 years).

Total age-dependency ratio is defined as the sum of young- and old- age dependency ratios.

3.5. Statistical unit

The statistical unit varies according to the data type as follows:

•           Persons - for data referring to the projected population;

•           Number of events - for data referring to the projected number of live births, deaths and international net migration (including statistical adjustment); and

•           Rates – for age-specific fertility and age-specific mortality rates.

3.6. Statistical population

Statistical population is the projected total population on 1st January as defined in 3.4. Statistical concepts and definitions.
