number of people with a different nationality that have a corresponding
migrant background. Apart from few exceptions,
persons with a different nationality are German citizens who
either also hold citizenship in one of the countries covered or
who used to hold such citizenship, or those who were born, or
whose parents were born, in one of the corresponding countries
of origin. Individuals with both a German and a relevant foreign
nationality could not be taken into account when extrapolating
the number of foreign citizens, due to the fact that Germans
with an additional nationality are not recorded in the AZR,
and that foreigners are deleted from the AZR after they have
obtained citizenship. 3 per cent of the individuals who demonstrate
a suitable migrant background on account of other characteristics
are neither citizens of the countries of origin covered
nor Germans, but rather nationals of a different country of origin
(e.g. French citizens who were born in Morocco). They have
been added to the group of Germans with a relevant migrant
background for the purposes of this extrapolation, and have
also been included linguistically with this group as a result of
the small number of cases.
In contrast to individuals with a relevant foreign nationality,
the number of whom is compiled in the AZR, the number
of Germans (and the small number of other individuals with a
different nationality) with a migrant background from the relevant
countries of origin is unknown. This means that multiple
steps are necessary in order to estimate the number of German
Muslims with a relevant migrant background. In the first step,
the corresponding total number of individuals in Germany who
come from the predominantly Muslim countries of origin being
covered is calculated for the individual countries and country
groups. For this purpose, the shares of Germans with a relevant
