Blacks make up 10% of the population......probably not enough to significantly effect life span statistics. 13.4% not 10% infoplease.com TABLE 12B: LIFE EXPECTANCY BY AGE GROUP AND RACE, IN YEARS, 1997 LIFE EXPECTANCY AT BIRTH WHITE 77.1 BLACK 71.1 All races: 76.5 efmoody.com 13.4% is about 1 in 7.5 (or 2 out of 15) X=All races life expectancy Y=Black life expectancy Z=Non Black life expectancy 2Y+13Z/15=X (271.1) + (1376.5) / 15 =X X=75.78 75.78 is too precise, but it should be approximately correct. So the lower life span of black people would lower the average American life span by about 75.8 - 71.1 or about 4.7 years. That's using 1997 data, and there is rounding involved, but it would probably have to be at least 4 years and it could be more than 5. If I did my math wrong I'm sure I'll be called on it, but while I did round off to make it easier I don't think I made any mistake with setting up the equations or doing the calculations.
