Of the religions in Denmark, the most prominent is the Evangelical Lutheran Church of Denmark which is the official state religion. However, pockets of virtually all faiths can be found among the population. The second largest faith is Islam, due to mass immigration in the 1980 and 90s.
In general, Danes are not very religious, with church attendance being generally low. According to a 2005 study by Zuckerman, Denmark has the third-highest proportion of atheists and agnostics in the world, estimated to be between 43% and 80%. Another study by Eurobarometer Poll 2005, 31% of Danish citizens responded that "they believe there is a god", whereas 49% answered that "they believe there is some sort of spirit or life force" and 19% that "they do not believe there is any sort of spirit, god, or life force". Though Christmas is considered to be Denmark's most celebrated holiday, this is mostly due to cultural, rather than religious, reasons.
By the end of 2007, 82.1% of the Danish population were members of the Evangelical Lutheran Church which dropped to 81.5 % in 2008 . However, similar to the rest of Scandinavia, North-west Europe and Britain, only a small minority (less than 10 % of the total population) attends churches for Sunday mass. In Copenhagen, membership of the Danish state church dropped to 65% in 2008.
With the exception of the Minister for Ecclesiastical Affairs (and only some of them), politicians will not generally be found using religious rhetoric and arguments, especially not government ministers. The Christian Democrats is the only major political party which regularly uses religious rhetoric and arguments and their influence is very low with less than 2% of voters backing them.
Also, there are about 500 registered heathens (0.01% of the population) belonging to the old Norse beliefs.
The Constitution of Denmark contains a number of sections related to religion.
