A few years ago PLoS Medicine published Eight Americas: Investigating Mortality Disparities across Races, Counties, and Race-Counties in the United States. The results were: -- Asian-Americans, per capita income of $21,566, life expectancy of 84.9 years. -- Northland low-income rural Whites, $17,758, 79 years. -- Middle America (mostly White), $24,640, 77.9 years. -- Low-income Whites in Appalachia, Mississippi Valley, $16,390, 75 years. -- Western American Indians, $10,029, 72.7 years. -- Black Middle America, $15,412, 72.9 years. -- Southern low-income rural Blacks, $10,463, 71.2 years. -- High-risk urban Blacks, $14,800, 71.1 years. That's a 13.8 year difference between inner city blacks and Asian Americans. Now, from The health and welfare of Australia's Aboriginal and Torres Strait Islander peoples 2003:
...Indigenous life expectancy at birth is 20 years less than for the total population, 56 years for Indigenous males compared to 77 years for all Australian males and 63 years for Indigenous females compared to 82 years for all Australian females for the period 1999-2001....
