Full name:

number of persons
Type of measure:
Arithmetic average, Population-weighted country group average
Data source:

Data source notes:
The following abbreviations are used in the indicator titles:
•    SDR: age-standardized death rates (see HFA-DB user manual/Technical notes, page 13, for details)
•    FTE: full-time equivalent
•    PP: physical persons
•    PPP$: purchasing power parities expressed in US $, an internationally comparable scale reflecting the relative domestic purchasing powers of currencies.

Indicator notes:
Mid-year population
Indicator code: pop.Publish.T

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._

2011 marks a (slight) break. From January 1, 2011 the definition of the population imposed by
Eurostat was applied; this mainly means the integration of asylum seekers listed in the waiting
registry in our statistics. Also, the mid-year population is not calculated as an average anymore,
but is the observed registered population in the National Civil Registry.

Definition changed between 1995-1996 from 'de jure' to 'de facto' principles. Population estimate
for 1996 has been based on the 1991 census according to the 'de facto' principle, balance of
international migration 1991-1996 and natural increase for that respective period.
The population for 1995 was estimated by the 'de jure' principle which means that persons were
enrolled according to the place of permanent residence, regardless whether present or absent.
Temporarily present persons were not included in the total number of inhabitants.
Coverage: Data refer to population in government controlled areas.

Population estimates for Georgia from the early 1990s are particularly inaccurate due to armed
conflicts in the first half of the 1990s and unregistered migration. From 1993-1994 the Abkhasia and
Tzkhinvali regions, which are not under central government control, were not included in national
mortality and other health-related statistics. Population figures, that were used as denominators
for calculation of mortality rates and other indicators in the HFA-DB, have been adjusted to take
into account the non-reporting regions and migration. These figures may still be significantly
biased though and the interpretation of mortality-based and the majority of other indicator data for
Georgia during and after the 1990s should be done with caution, keeping in mind the relatively low
accuracy of raw data used for both numerator and denominator.

Coverage: The average population includes all persons, who have their (permanent) place of residence
in the federal territory. Foreign employees who live in the federal territory are included. Members
of the foreign armed forces are not included.
Estimation method: The data of the annual average population for one calendar year is the arithmetic
average of 12 monthly averages. The monthly averages are calculated from the state of population at
the beginning and at the end of a month.
Break in time series: The population numbers prior to 2011 are taken from the Update of the
Population based on earlier censuses (Former Federal Republic of Germany 1987, German Democratic
Republic 1990). Starting from 2011 the population numbers are based on the Federal Census (census
data as of 27 November 2015). Therefore, for the years from 2011 onwards differences to previous
publications of population related numbers are possible.

Source of data: Census and current statistics on natural movement and migration of population.
Current estimates of the resident population on 1 January of given calendar year are calculated on
the basis of the results of the last census adding annually the number of births and arrivals on a
given territory and subtracting the number of deaths and those who left given territory. This takes
into account changes in the population resulting from administrative-territorial reforms.
The National Bureau of Statistics (NBS) receives data on the natural movement of the population from
the Ministry of Justice (Civil Status Service). The databases of administrative sources: Ministry of
Information Technology and Communications (State Information Resources Center ®Registru¯) and the

Coverage: From 1997, livebirth and mortality data (plus population data used to calculate mortality
rates), do not include data for Transnistria. From 2004, total population figures published in
HFA-DB exclude Transnistria. Data on the natural growth of the population include individual cases
of registration of births and deaths of inhabitants of Transnistria and Bender municipality. The
migration growth included in the current calculations of population differs from the reporting data
due to amendments in some cases of relocation of residents of Transnistria and Bender municipality.
