The study exemplifies the use of an institutional-territorial approach for a comprehensive description of a national denominational landscape. The article aims to provide such an account by analysing relevant official data and performing statistical processing using computational tools. The focus is on the Evangelical Lutheran Church of Denmark and its administrative-territorial structures. The study places emphasis on the financial aspect, one seldom discussed in academic discourse. The denominational landscape of Denmark is a multicomponent system, with the National Lutheran Church holding a distinctive legal status as a dominant entity. Its historical and social significance, along with the ability to preserve functions that mirror those of the state, allow the Church of Denmark to maintain its civilisational and culture-building role for the populace, especially the indigenous one. However, Denmark is not exempt from the secular trends prevalent in the Nordic countries. One notable tendency is the decline in adherents of the Evangelical Lutheran Church observed over recent decades. This decline is most evident in the capital region, where the proportion of migrants in the population is higher and daily life is more vibrant than in other areas. Territorial variations in religiously motivated behaviour are evident, with the highest percentages observed in the country’s peripheral regions (despite the overall figures showing a negative trend). These areas also boast the most significant proportion of registered members of the Evangelical Lutheran Church. Exploring non-Christian religions in Denmark presents a promising avenue for future research.
