<P> The Lutheran Church of Sweden -- which was the state religion until 2000 -- has a registered membership of 6.1 million Swedish citizens , equal to 61.2 % of the total population . One reason for the high membership might be the fact that until 1996 all newborns with at least one parent being a member of the Church of Sweden were also registered as members of the church . Yet the membership is declining rapidly , about 1 % each year , falling from 95 % in 1970 and 85 % in 2000 . </P>
