I recommend double checking reference tables in Wikipedia.

It is conveniently displayed first in search results, however for Sweden:

  > 305 Completed murder, manslaughter and assault resulting in death.
  > 9,851,017 Total population

= 3.1 per 100000 people

The differences are due to different definitions of intentional homicide between countries, which is why I would argue a UN study with its own definition is better for comparison than a Swedish and US source.
