Population at the end of 2022 and components of population change (vital events and migration events, statistical adjustments)

Vital events are based on data provided by the registrar offices; Migration events are based on data provided by the population registers

Statistical adjustments are made to take into account events which are registered in the reference year but occured earlier than the previous year and corrections made in the registers.

Counts of statistical units

The reference date for population data is the end of the reference period (midnight of 31 December).
The reference period for vital events data is the calendar year in which the events occurred.
The reference period for migration flow data is in principal the calendar year in which the migration was registered.

Events registered in December but only transmitted in January of the following year to the statistical offices are however included in the reference year.

With this exception, events which were transmitted in the reference year but occured in the previous year are counted in the flow statistics.

As described in quality report

All data included in intercensal population updates were previously subject to a variety of measures to assure the quality of the data in the statistical
production process. Data received are subject to continuous plausibility checks and are checked for double countig. The data included in intercensal population updates are
administrative data. If a data provider detects errors in its data, it corrects them and sends the corrected data to the responsible statistical office, so
that the intercensal population update can be corrected.

The quality of intercensal population updates depends to a large extent on the quality (completeness, accuracy) of the statistical results included in the calculation. All elements of intercensal population updates are based on complete counts. The system of intercensal population updates ensures high coherence of the different sets of population statistics because all statistics included in the updates are produced using the same concepts, definitions and classifications. The components of population development (live births, deaths, migrations) are consistent and their reliability is generally high or very high. However, intercensal population updates require regular adjustments by way of a new population census. As time elapses since the last census, inaccuracies (overcoverage or undercoverage in individual groups of the population) accumulate in the intercensal population updates. The last adjustement occured with the 2011 census.

Population data are needed for a wide range of users for administrativ, planing, statistical, scientific and economic purposes and are of general interest for the society.

Data contents meet all the legal requirements.

The final data were published 6 months after the end of the reference period:

Final results on population stocks on 31 December 2022: 20.06.2023

Final results on immigrants and emigrants 2022: 27.06.2023

Final results on vital events 2022: 03.07.2023

Provisional results on vital events and migration were available in April 2023

Data were published punctually.

Data are processed using the same method and the same procedure, so that the geographical comparability within Germany is considered to be very good.

Not available

Demographic balance is coherent as all statistics are based on the same population concept.

Provisional data on vital events and migration are revised with the final annual results. The results on population stocks on 31 December 2022 based on census 2011 will be revised with the data based on census 2022. 

Provisional data on vital events and migration are revised with the final annual results. The results on population stocks on 31 December 2022 based on census 2011 will be revised with the data based on census 2022. 

Data are collected online on a day to day basis.

The registrar's offices and population register offices automatically send data on registered events to the statistical offices of the Länder. After validation of the data, the statistical offices of the Länder monthly transmit summary data on flows to the Federal statistical office for computation of the national results. Intercensal population updates are calculated in a decentralised way by the statistical offices of the Länder for their territory in the common data processing system of the Federation and the Länder and are made available to the Federal Statistical Office.

There is a validation of single data on vital events and migration by checking for double counting and plausibility of data and partly for completeness through the statistical offices of the Länder. Results of each flow statistic as well as the results of intercensal population updates are checked for global plausibility and consistency by expert assessment at the statistical offices of the Länder and at the Federal statistical office. Data delivered more than once as well as irrelevant data such as events which occurred prior to the last census are deleted. Missing or not plausible variables are either imputed or are filled/corrected after clarification with the data provider. Variables are coded using national statistical classifications (e.g. classification of territorial units, classification of countries). 
Corrections to previous data received from the data providers are processed and, if relevant, are taken into account in the calculation of population figures. Corrections are taken into account in the statistics on vital events and on migrations if the corrected event occured in the same year.

In the case of administrativ deregistrations where the new place of residence is not known, it is assumed that the person left Germany and is to be counted in the emigration data.
