The rate of change in human development outcomes varies considerably across countries over long periods of time, as reflected in the two histograms below (Figure 1). For 78 countries in the period 1980-2014, the percentage decline in child mortality was 3.39% on average, with a standard deviation of 1.36%, a smallest rate of 0.89% (Central African Republic) and a highest rate of 8.07% (Maldives). The average percentage increase in school enrollment was 3.35%, with a standard deviation 3.54%, a minimum of 0.37% (Georgia) and a maximum of 19.68% (Maldives). Similar patterns of cross-country variation are found when using alternative proxies for health and education outcomes.
The extent to which people across the world have access to clean water, education, food, healthcare and other basic needs is measured by the Millennium Development Goals (MDGs), a set of internationally agreed targets adopted in 2000. Last week, world leaders and the developmental community gathered in New York for the MDG summit to urge the international community to speed up progress toward the MDGs.
