Muslim Life in Germany - Deutsche Islam Konferenz

How many Muslims live in Germany? 59
Calculation of the number of Muslims was performed in
four steps:
Calculation of the country- or country-group-specific
95% confidence intervals for the share of foreign Muslims
on the basis of the survey data. This results in an
interval for each country or country group with a minimum
and maximum share in which Muslims’ share of
the total population should fall with a probability of 95
per cent. Extrapolation of the minimum, determined
mean and maximum shares on the basis of the AZR
data and determination of the minimum, mean and
maximum number of Muslims with corresponding nationalities
in Germany for the individual countries or
country groups. Summation of the country and country
group values in order to determine the total sum
for the number of foreign Muslims from the countries
of origin covered.
Determination of the total number of individuals with
a migrant background from the countries covered
on the basis of the AZR data and the relation between
foreign persons from the corresponding countries of
origin to those Germans with a migrant background. 28
Once this has been done, the figure determined in
each case for persons with a migrant background from
the country or country group in question is multiplied
by the share which has been calculated for Germans
with a relevant migrant background or with the mini-
28 The total number of persons with a migrant background for each country of
origin is determined using the following formula: (p * persons in the AZR / 100 *
p) + persons in the AZR, whereby p is the share of Germans with a migrant background.
