According to polls among Muslims in Denmark conducted in 2006 and 2018, religiosity shows an escalation over time, whereas 37% prayed five times a day in 2006, by 2018 this number had increased to 50%. This was contrary to expectation where Muslims had been expected to conform to mainstream Danish society where not many people are not particularly devoted to religion. The possible cause of the trend, according to sociologist Brian Arly Jacobsen at Copenhagen University was that in the construction of 20-30 new mosques in the intervening 10 years.[27]
