* The US is thought by some economists to have an artificially high infant mortality because the US is more rigorous about reporting live births than other countries which might write up the same events as stillbirths.
* Outcomes in the US for chronic serious illnesses are at or near the top of the rankings.
* Life expectancy figures in the US are anchored down by suicides and, more importantly, traffic fatalities, which the US leads the world in. While that's not something we should be OK with, it's also a direct consequence of the vast land mass and wide population dispersal in the US.
