With 3.9 million members, the Evangelical Lutheran Church of Finland is one of the largest Lutheran churches in the world and is also by far Finland's largest religious body; at the end of 2019, 68.7% of Finns were members of the church. The Evangelical Lutheran Church of Finland has seen its share of the country's population declining by roughly one percent annually in recent years. The decline has been due to both church membership resignations and falling baptism rates. The second largest group, accounting for 26.3% of the population in 2017, has no religious affiliation. The irreligious group rose quickly from just below 13% in the year 2000. A small minority belongs to the Finnish Orthodox Church (1.1%). Other Protestant denominations and the Roman Catholic Church are significantly smaller, as are the Jewish and other non-Christian communities (totalling 1.6%); for example, in the Protestant trend, there are about 1,500 Baptists concentrated in the region of Central Finland, and there are only about 2,000 Methodists who are scattered around the country. The Pew Research Center estimated the Muslim population at 2.7% in 2016. The main Lutheran and Orthodox churches are national churches of Finland with special roles such as in state ceremonies and schools.
