Trends in the educational gradient of U.S. Adult mortality from 1986 through 2006 by race, gender, and age group

The educational gradient of U.S. adult mortality became steeper between 1960 and the mid-1980s, but whether it continued to steepen is less clear given a dearth of attention to these trends since then. This study provides new evidence on trends in the education-mortality gradient from 1986 through 2006 by race, gender, and age among non-Hispanic Whites and Blacks using data from the 2010 release of the National Health Interview Survey Linked Mortality File. Results show that for White and Black men, the gradient steepened among older ages because declines in mortality risk across education levels were greater among the higher educated. The gradient steepened among White women, and to a lesser extent among Black women, because mortality risk decreased among the college-educated but increased among women with less than a high school diploma. Greater returns to higher education and compositional changes within educational strata likely contributed to the trends.
