IHME research, published in The Lancet, provides estimates of the educational attainment of men and women for 175 countries by age group and sex, and includes confidence intervals. The study, "Increased educational attainment and its impact on child mortality: a systematic analysis in 175 countries from 1970 to 2009," examines gains in women's education and their contribution to declines in child mortality in the past 40 years.
