Life Expectancy at All-Time High, But What Does it Mean?
Tuesday, September 15th, 2009The Natonal Center for Health Statistics of the Centers for Disease Control and Prevention reports that life expectancy of Americans at birth reached an all-time high of 78 in 2007. This ranks us 35th in the world, right behind Portugal and Ireland.
Women do better than men with a life expectancy of 80 years as opposed to 75 for men, and whites do better than blacks, whose life expectancy at birth is only 73 years.
However, according to the report “Deaths: Preliminary Data for 2007“ it’s black men who do the worst. Their life exectancy of 70 is seven years less than black women, whose life expectancy of 77 is higher than white men’s life expectancy of 75.
Alzheimer’s disease moved up from the seventh to the sixth cause of death between 2006 and 2007. However, it is dwarfed in numbers by the two leading causes of death, heart disease and cancer.
While this information is interesting, it leaves a lot out. Is life expectancy increasing because seniors are living longer or because more people are making it to their older years? What is the life expectancy of people at age 65? Are these extra years good years, or are they spent ill and demented? Do the discrepancies between men and women and between whites and blacks apply equally at all ages? For instance, are men and blacks (and especially black men) more at risk of death when they are young, or do those who survive to middle and old age also die so much younger than women and whites?
