Quoted from KerryImming:Actually age seems to be the biggest factor.

If that doesn't open to a chart by age scroll down to "Age Group Data Table".
Those statistics don't mention anything about weight groups that I can see. So it really doesn't disprove the hypothesis I made.
Is it possible that a high percentage of those in the age groups of the highest risk are also obese?
As far as age group comparison, some age groups have far fewer people than others to begin with.
