Region of birth and mortality of blacks in the United States.

Analysis of black American death rates by region of birth and region of residence showed that southern-born blacks had the highest mortality rates and western-born blacks the lowest mortality rates. Blacks born in the northeast, midwest, and outside the US had rates intermediate between southern and western-born black rates. Blacks born in one region and who died in another had age-specific and age-adjusted mortality rates similar to their region of birth rather than their region of residence.
