@Plina - you say you live in a secular country, but you fund your churches through taxes - am I reading right?
Apologize for dropping an unexplained abbreviation - UU = "Unitarian Universalism". That's the denomination I was referring to - the Unitarians the jrhampt refers to. Tiny, but among the most liberal Christian denominations, at least by party registration of members in the United States anyway.
Actually, I learned it is not a tax but a churchfee, like a membership fee. It is apparently legislated through a law from 2000 when the church was separated from the state. If you fill the requirement for a denomination?/church organisation the tax authorities can help the organisation to collect the fee. There are apparently 17 of those that have asked for help. As a member I pay 1 % of my taxable income as a church fee to the Swedish church, but you seem to have catholic, methodist, muslim organisations among others. You become a member of the Swedish church by baptism as a kid or later in life. Previously, you became a member by birth but that is no longer the case. It is not a requirement to be a member of any of the organisations, with one exception. The head of the state, the king or the queen, has to be a member of the Swedish church.
You actually also pay a burial fee through the tax authorities to the Swedish church that is responsible for the upkeep of the cementaries. That is mandatory for everyone.
So why do I still say that Sweden is seen as a pretty secular country? Because, most of the people are members by habit or because they have to take action to quit their membership that my generation got automatically. Personally, I am still a member because I like to contribute to preservation of all the old buildings. Religion is also seen as something personal. I frankly only know one person that have ever mentioned visiting a church for sermons and she belonged to a nonconformist church. I can't remember a politician from the bigger parties talking about their faith. We have a Christian Democratic Party but they got about 6 % of the votes. So even if many are members, they are not active members.
The visits to services at the Swedish church are declining, In 1990, there were about. 24 million visits and 2019 about 13 million visits. About 3,4 million of those in 2019 were for Sunday service and 4,9 million for baptism, weddings, funerals (you don't need to be a member to be counted into this number). That is with 5,8 million members, which is more than half of the population. Most of the people I know visit the church for funerals, baptism and weddings, while Sunday services are for old people, at least in the Swedish churcht. I have been twice in a church this year, once for a funeral and once for a baptism.
