At the end of 2018, 57.7% of Swedes belonged to the Church of Sweden; this number had been decreasing by about 1.5 percentage points a year for the previous 7 years and one percentage point a year on average for the previous two decades. Approximately 2% of the church's members regularly attend Sunday services. The reason for the large number of inactive members is partly that, until 1996, children automatically became members at birth if at least one of the parents was a member. Since 1996, only children and adults who are christened become members. Some 275,000 Swedes are today members of various Evangelical Protestant free churches (where congregation attendance is much higher), and due to recent immigration, there are now some 100,000 Eastern Orthodox Christians and 92,000 Roman Catholics living in Sweden.
