US blog Decisions Based on Evidence highlights some research from the States on differences in life expectancy on the basis of ethnicity and educational achievement.  The summary puts it starkly: “Despite advances in health care and increases in life expectancy overall, Americans with less than a high school education have life expectancies similar to adults in the 1950s and 1960s."  The study's authors conclude: "The message for policy makers is clear: implement educational enhancements at young, middle, and older ages for people of all races, to reduce the large gap in health and longevity that persists today."
