Population aged 0–14 years

Calculated from European Health for All database indicators "% of population aged 0–14 years" and " Mid-year population".
Population aged 0-14 years Estimate of resident (de jure) population on 1 July of given calendar year. Usually, it is calculated as an average of end-year estimates. The central statistical office (CSO) is the source in most countries. This data item is used as denominator to calculate most other indicators. Although "de facto" population would be preferable, the "de jure" population is used because it is more commonly available, particularly in age-disaggregated form. However, in case of some countries, particularly in those which were effected by war situation in 1990s, the difference between official population estimates and actually residing in country population (i.e. de facto) may be too large. In such cases special efforts should be made to provide also estimates for "de facto" population to be used as a denominator. Since 2000 data collection cycle, a separate entry for "de facto" population is provided (indicator 999997).WHO usually receives mid-year population by sex and age, together with annual mortality data. However, for some countries there is a delay of 2 or even more years in reporting mortality and population by age, making it impossible to calculate many indicators for which numerator data are available for more recent years. In such cases, countries are expected to provide at least provisional figures on total population by sex only, these will be automatically replaced later with the final population data from the mortality data reporting system. If these data are not available, UN population estimates (based on projections) are used for the most recent year until they are replaced by national estimates received from countries. In some case this may cause some inconsistent trend for the latest year.
