3.1. Data description

The datasets are composed by the baseline population projections and five sensitivity tests, namely:

  • no migration – it is assumed that the net migration is set to zero in each year of the entire horizon of projections;
  • lower migration – it is assumed that the net migration is 33% lower than in the baseline assumptions, in each year of the entire horizon of projections;
  • higher migration – it is assumed that the net migration is 33% higher than in the baseline assumptions, in each year of the entire horizon of projections;
  • lower fertility - it is assumed that the fertility rates are lower 20% than in the baseline assumptions, in each year of the entire horizon of projections;
  • lower mortality - it is assumed that the mortality rates are decreased such that the life expectancy at birth will increase of about two years by 2070 when compared with the baseline assumptions.

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, probabilities of dying and net migration levels;
  • Corresponding approximated values of the life expectancy at birth by sex.

Moreover, the 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 ages of the population.

The time horizon covered is: 2019 to 2100.

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 January 2019 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.

Probability of dying is defined as the ratio between the number of persons who reached the exact age x and the number among them who did not reached the age 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), young persons (0-19 years), two age groups for persons in the working-age (15–64 years, and 20-64 years ), elderly (65 years and over) and oldest-old persons (80 years and over) in the total population.

Young-age-dependency ratio - two ratios are available according to the age groups used to classify the persons as 'young' and in the 'working-age':

1) the young-age-dependency ratio - defined as the ratio between the number of persons aged 0-14 over the number of working-age persons (15-64 years);

2) the young-age-dependency ratio - defined as the ratio between the number of persons aged 0-19 over the number of working-age persons (20-64 years);

Old-age-dependency ratio - two ratios are available according to the age group used to define the persons in the 'working-age':

1) the old-age-dependency ratio - defined as the ratio between the number of persons aged 65 years and more over the number of working-age persons (15-64 years);

2) the old-age-dependency ratio - defined as the ratio between the number of persons aged 65 years and more over the number of working-age persons (20-64 years);

Total age-dependency ratio is defined as the sum of young- and old- age dependency ratios, based on the common age group used to define the persons in the 'working age'.

3.5. Statistical unit

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

  • Person - for data referring to the projected population and net migration;
  • Number of events - for data referring to the projected number of live births and deaths;
3.6. Statistical population

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

3.7. Reference area

EU Members States and EFTA countries (Iceland, Liechtenstein, Norway, Switzerland)

3.8. Coverage - Time

From year 2019 to 2100.

3.9. Base period

1 January 2019.


4. Unit of measure Top

The specific measurement units vary depending on the population projections tables as follows:

  • Person - for all data on projected population and migration;
  • Number - for data on vital events (live births and deaths); and
  • Years - for data on approximated life expectancy at birth and median age.
