The inventory team of the Single National Entity has decided to use this corrected population time series for all relevant calculations.  As a result, various time series have been recalculated from 1991 up to and including 2016.    * several NFR categories: revision of __population data__: The population in Germany has been subject to several evaluations in recent years.  In the meantime, the methodology for the so-called "Census 2011" has been confirmed by the Federal Constitutional Court in the final instance with a representative survey and extrapolation by the Federal Statistical Office.  On this basis, the Federal Statistical Office examined correction options for previous years and published a so-called "recalculated and extrapolated population on the basis of the 2011 census".  This recalculation up to and including 1991 eliminates the gap between the 2010 population updates and the 2011 census results.
