Actually it's easy. Just take maternal deaths. The US is pretty straightforward in maternal deaths and baby deaths. If an infant is born alive, and dies, it is an infant death in the US. Even if it is completely nonviable (e.g. no heart). In the Netherlands any baby that dies in < 2 weeks after birth is not an infant death. If a child dies < 5 years it is not counted in life expectancy calculations. I'm not sure what the situation in the US is. But frankly, any time a number sounds extreme (and this one does) your first thought should frankly be "how have governments faked this number". Just like for private companies, if a number sounds too good to be true, it almost always is. So the numbers aren't as comparable as people claim. There is obviously a difference, but it's not as dramatic as advertised.
