I rather strongly doubt the "Norway has zero" statement. It does not directly reference any study nor does any other article stating the same. I don't doubt that it is lower or even rounds to 0 per 100,000, but actually 0 is almost certainly wrong.
In 2021 [0], the deaths per 100,000 in Norway was 1.7 which is ~80 maternal deaths. I find it hard to believe that Norway happened to go from 80 to 0 in two years even including a generous amount of luck.
