Christianity is the predominant religion of Denmark, with 80% of the Danish population estimated as adherents of the "Folkekirken" ("People's Church"), Denmark's national Lutheran church.[4] Aside from Lutheranism, there is a small Roman Catholic minority, as well as small Protestant denominations such as the Baptist Union of Denmark and the Reformed Synod of Denmark.
Denmark is today a very secular country, but has a culture that is heavily influenced by Christianity.
