The poll, published on Thursday, found that 34 percent of respondents believe Islam is a part of Germany, which has a population of between 2.1 million and 4 million Muslims.
The figures show a significant shift in public opinion since 2010, when the then German President Christian Wulff said in a speech that Islam is part of Germany. At the time, 49 percent of respondents agreed with the president while 47 percent rejected his statement.
Reservations over Islam were also more apparent among older Germans, with 71 percent of those aged over 64 stating that Islam does not belong to Germany. In contrast, almost half of Germans aged between 18 and 34 said that Islam does belong there.
Concerns over influence of Islam
The survey, carried out by Infratest dimap for German public broadcaster WDR, comes amid growing skepticism towards Islam in Germany, particularly among supporters of the right-wing Alternative for Germany (AfD) and free-market Free Democratic Party (FDP).
