3.1. Data description

The Total Fertility Rate is the most common period indicator of fertility, measuring the average number of live births a woman would ever deliver if she were toexperience the fertility rate of a given period. It is computed as the sum over childbearing age of age specific fertility rates, in their turn computed as the ratio of the number of live births from women of a given age to the number of women of the same age exposed to the risk of childbearing.

3.2. Classification system

3.3. Coverage - sector

See demo_pop_esms

3.4. Statistical concepts and definitions

See 3.1. Age concept: most National Statistical Institutes of the EU Member States provide data on the number of live births: mother's age and mother's year of birth. Live births are compiled and disseminated, based on the data collected, as follows: by mother's age at last birthday (also referred as age completed) and by mother's age reached during the year. The availability of data on live births by the two concepts among the countries starts at different moment of time series.

Eurostat uses the concept of age completed for the calculation of the fertility indicators.

6.1. Institutional Mandate - legal acts and other agreements

Until Reference year 2012, data needed to calculate the indicator were collected from National Statistical Institutes and on voluntary basis. Starting from reference year 2013, EP and Council Regulation No 1260/2013 on European demographic statistics and related Commission implementing regulation No 205/2014 will enter into force.

6.2. Institutional Mandate - data sharing

The demographic data collection is carried out in cooperation with the UNSD.

12.1. Relevance - User Needs

The Total Fertility Rate is a central indicator to assess the fertility of a population. It adds the age specific fertility rates observed during the reference year, i.e. the average number of children born to women of a given age in relation to the number of women of that age. This rate is therefore the completed fertility of a hypothetical generation. The indicator is independent from the age structure of a population, i.e. of from the number of women having a certain age, and is therefore particularly useful for international comparisons or for comparisons over time.
Future population size and age distribution within that population are to a very large extent determined by the total fertility rate. It is generally considered that at a level of 2.1, other things being equal, the total fertility rate would lead to a more-or-less stable population size and age distribution.
A change in the fertility rate also impacts on the balance between the generations. Demographic statistics on the size and structure of Europe's population are used in a wide range of economic, social and environmental policy areas.

15. Coherence and comparability Top
15.1. Comparability - geographical


Eurostat requests to all countries demographic statistics based on the concept of usual resident population. In accordance with this concept, the following persons are considered to be usually residents of the geographical area in question: those who have lived in their place of usual residence for a continuous period of at least 12 months before the reference date or those who arrived in their place of usual residence during the 12 months before the reference date with the intention of staying there for at least one year. Countries may provide however the legal or registered population instead of the usually resident population.

In addition, Eurostat requests data on population referring to 1 January. Countries may collect data at national level using a different reference date: for most of them, 1 January or 31 December of the previous year is used but some countries may refer to mid-year or another date. However, population data on 1 January are estimated and transmitted to Eurostat. The population is based either on data from the most recent census, adjusted by the components of population change produced since the last census, or on population registers.

Eurostat calculates all demographic indicators for all countries and all geographical aggregates using a common methodology.

17. Data revision Top
17.1. Data revision - policy

Generally speaking, the data on demographic vital events are revised on a continuous base according to updates and revisions provided by the national statistical institutes. The aggregated geographical levels are updated accordingly.

18. Statistical processing Top
18.1. Source data


Data are collected by Eurostat from the National Statistical Institutes.

18.2. Frequency of data collection


18.3. Data collection

The annual demography data collections at country level are carried out by Eurostat from the National Statistical Institutes in order to collect detailed updated demographic data. See section 6.1.

18.4. Data validation

Cross validations are carried out to check consistency between the different tables of one domain. When demographic indicators are calculated, other errors can be detected in the time series by country and they are investigated.

18.5. Data compilation

 Geographical aggregates are sometimes estimated in case a component geographical unit missing (i.e. data are not available for all countries that constitute the aggregate). No estimations done by Eurostat for the national data are published under this situation, but only the demographic indicator(s) resulted for the aggregated geographical level, marked with a correspondent flag for estimation.

18.6. Adjustment
