| 1 1961 and 1970: Population Census results; other years: Microcensus results (1975: results of the EG Labour Force Survey). 1961 to 1969 and 1971: population entitled to accommodation; 1970 and from 1972: population in households. From 2005: With the Microcensus Law 2005, the microcensus was changed from a survey with a fixed reference week (up to 2004 generally the last week without holidays in April) to a continuous survey with a moving reference week. The results as from 2005 thus have provided information on the entire development on an average of the reference year instead of giving a 'snapshot' of a specific calendar week. The methodical changes involved in the introduction of the moving reference week have led to variations in the number of households, especially of one-person households and of the families/ways of life. From 2011 the population projection is based on data from the 2011 Census; the results cannot be compared with previous years. 2 Until 1990: former territory of the Federal Republic. Differences in totals due to rounding. Further information on methodological effects in time series of social statistics (statistics of private households and families) based on microcensus (only in German). |
