Despite stagnation in the economy, Iran's Human Development Index rating (including life expectancy, literacy, education, and standard of living) improved significantly in the years after the revolution, climbing from 0.569 in 1980 to 0.759 in 2007/8. It now ranks 94th out of 177 countries with data. This is approximately the same rate, as neighbor Turkey which has a somewhat higher HDI rating (0.775). One factor in the HDI rise has been literacy rates among Iranian women which "rose from 28% to 80% between 1976 and 1996."
