Here’s the UN’s rundown on estimated current rates of infant mortality per 1000 births. The US’s similar rundown by state is a little hard to read, so I turned to the book State Rankings 2003: A Statistical View of the 50 United States. There are lists ranking the states by various statistical measures, one being infant mortality. The premise here is that one could compare the mortality rate of each state to other countries, since the rate in the US varies quite a bit state to state. Well, it looks like the range in the US is like the range in Europe. Some states are Germany, while others are Hungary.
