Check out Sweden in that link and the two neighbors, Norway and Finland.
Sweden didn't do much of anything except perhaps notify the population.
Well, here you go:
US 633/mil
Sweden- 581/million
Norway- 50/mil
Finland- 62/mil
They are certainly equals in healthcare, density, and others.
India, huge population and areas of density: 70/ mil
Brazil, didn't do much for the citizens : 666/mil
