Measuring the Development Progress of Least Developed Countries: In the Context of World Development

This article measures the ten-year development progress of 47 least developed countries (LDCs) based on comparing the development performances of 217 countries and economies. A methodology based on the theory of statistical process control is used to evaluate development performances in three dimensions: per capita income, life expectancy, and education. This methodology uses a pair of average and standard deviation charts to measure each LDC's degree of growth and stability of growth in each dimension of development, and uses the three standard deviation limits in each chart to identify exceptional development performances that are outside the upper or lower limit. This article has three key findings on the exceptional development performances of LDCs in the context of world development over 2010–2019: (1) Seventeen LDCs achieved exceptionally high increases in life expectancy; (2) one LDC achieved exceptionally high growth in per capita income, but two LDCs had exceptionally low performances in the growth of per capita income; and (3) six LDCs experienced exceptionally unstable growth of per capita income. These findings shed some light on the future development priorities for LDCs. The reliability of analysis is also discussed.
