According to the latest figures, Germany's Muslim community numbers close to 4 million people, or about 5 percent of the entire population. Past estimates put the number of Muslims in the country at 3.1 to 3.4 million.
Additionally, the survey funded by the Interior Ministry found that Germany's Muslim community is very diverse.
To get a better sense of the views and customs of German Muslims, researchers phoned 6,000 households with 17,000 residents. The pollsters asked a variety of questions, such as whether the family ate pork or drank alcohol.
