According to official statistics from January 2019, 74,7% of the population of Denmark are members of the Evangelical Lutheran Church of Denmark, the country's state church since the Reformation in Denmark–Norway and Holstein, and designated "the Danish people's church" by the 1848 Constitution of Denmark. This proportion is down by 0.6% as compared to the preceding year and 1.2% down compared to two years earlier. However, in similar fashion to the rest of Scandinavia, and also Britain, only a small minority attends churches for Sunday services. In addition, the number of people leaving the Church has been on the rise: in 2012 21,118 Danes left the Church, an increase of 55% in comparison to 2011. Individuals automatically become members when baptized, as most people born in Denmark are at birth, and cannot leave of their own accord until they are 18 years old. Members are not informed of their membership or their ability to leave. Further, there are no standard formulas for leaving the church; one must personally contact the priest or office of one's parish.
Other Protestant groups
A small Baptist community has existed since the 1840s, and is represented by the Baptist Union of Denmark. The Union claimed 55 churches and 5,412 congregants in 2011. Reformed Protestantism is represented by four churches united in the Reformed Synod of Denmark. These are mainly ethnic congregations, including two Huguenot churches and a German Reformed church, founded in the seventeenth and eighteenth centuries, as well as the Korean Reformed Church founded in 1989. The German Reformed church also includes some Dutch, Swiss, Hungarian and American members, as well as Danes. There is an Anglican church and fellowship in Copenhagen and smaller congregations of Anglicans and Episcopalians in many Danish cities. A 2015 study estimates some 4,000 Christian believers from a Muslim background in the country, most of them belonging to some form of Protestantism.
Catholic Church
After the separation of the Church of Denmark from the Catholic Church in 1536, the Catholic Church remained illegal in the country for over three centuries. The Church was able to reestablish itself after the Constitution of 1849 granted religious freedom to the Kingdom. Currently the country is covered by the Diocese of Copenhagen with 48 parishes in Denmark proper and two more in the Faeroe Islands and Greenland. There are nearly 40,000 Catholics in Denmark, though nearly a third are foreign born and others are born of foreign parents. Nevertheless, ethnic Danes are still the largest group among the Church's congregants.
