R1b is found in much larger numbers in Norway, Sweden, and Denmark than is N. In Denmark R1b is the biggest haplogroup; in Norway it splits the population almost evenly with R1a and I1a (almost). Only in Sweden is I1a much larger than the other groups, and even there R1b is well represented.
I1a was in Scandinavia first, but was followed closely during the prehistoric period by R1b and R1a. R1b has been a long while in southern and western Scandinavia, which is why it is so populous there.
I think N came in last of all, from the East, which is, BTW, where the Finno-Ugrians came from and are still found to a large extent.
