This increase corresponded roughly to the increasing numbers of Muslims in the country, which had risen from 200,000 to about 300,000. 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%.

The Danish researcher Brian Jacobsen from University of Copenhagen, who makes regular estimations based on the national origin of immigrants and their descendants, estimates that by January 2020 Muslims made up 256,000 persons or 4.4% of the Danish population. One year earlier, Jacobsen had estimated the number of Danish Muslims to 320,000 persons, but adjusted his earlier estimates downwards after having accessed new and more precise data. Also the World Population Review. reported a figure of 313,713 Muslims living in Denmark, or approximately 5.40% of the population, in October 2019.
