Most Norwegians are registered at baptism as members of the Church of Norway, which has been Norway's state church since its establishment. In recent years the church has been granted increasing internal autonomy, but it retains its special constitutional status and other special ties to the state, and the constitution requires that the reigning monarch must be a member and states that the country's values are based on its Christian and humanist heritage. Many remain in the church to participate in the community and practices such as baptism, confirmation, marriage and burial rites. About 70.6% of Norwegians were members of the Church of Norway in 2017. In 2017, about 53.6% of all newborns were baptised and about 57.9% of all 15-year-old persons were confirmed in the church.
