The UAMS College of Public Health has issued a report that the mortality rate among Arkansas blacks is significantly higher than that of whites for most cancers, HIV and homicide, but lower for motor vehicle crashes and suicide.
Here's a link. NOTE: The original link went to an earlier, now outdated, report. There's much there on demographics — income, family structure, education — as well as health.
Correlation is not causation, I know, but you have to wonder if the generally much lower economic status of blacks might be a contributing factor in poorer health.
