Kohonen Self-organizing Maps as a Tool for Assessing Progress toward the UN Millennium Development Goals

This paper introduces Kohonen self-organizing maps to the scholarly discussion of the United Nations Millennium Development Goals (MDGs). We use data through the MDGs' approximate mid-point (2000--2008) to analyze three world regions: Africa, Asia and Latin America. We observe a handful of countries that showcase noteworthy progress, including Ghana, Senegal, China, Vietnam, India, and Brazil, and then examine more closely the three major regions of developing countries: Africa, Latin America, and Asia. Major statistical differences within Africa separate the northern and southern regions from the central, eastern and western regions. In contrast, Latin America and Asia are largely homogeneous in the MDG measures with the exceptions of Afghanistan, Haiti, and Bolivia, which lag far behind. The substantial differences between Africa and the other continents (and indeed within Africa itself) appear to be mainly attributable to deficiencies in education and information and communications technology infrastructure, both areas that are imperative for the achievement of other MDGs. The paper demonstrates self-organizing maps to be a useful tool in evaluating differential convergence over the three time periods under investigation.
