I've see that figure many times. One must take into account premature births and how stillbirths are reported. And also due to the racial makeup of America. Blacks have higher rates of infant mortality than whites.

Oh? Are black people not really counted for the purposes of birth stats? Why? Poorer genetics? Poorer healthcare access? Again, how would poorer healthcare access jibe with your "best in world" medical care?
I would love to see a good study that tries to disentangle the various correlations here...
