Agreed.

As a foreigner who moved to Sweden, it was quite shocking first to see all this info displayed online for everyone to see but there are definitely some good sides and bad sides to it.

One of the good side is that, you can look at the people living in a given area and decided if this is the kind of neighborhood where you want to live. Lower (declared income) can have a correlation with crime so if you just want to have a quite life, you may want to select an era that has loads of working people with a higher than average income.

One bad side, some people have used it in the past to harass people, think ex-lovers and so on. There is a procedure in place where if you are afraid of being stalked you can ask for your information to be removed from these registries or at least be hidden from public view.
