Development Economics

What we know as the developing world is approximately the group of countries classified by the World Bank as having “low” and “middle” income. An exact description is unnecessary and not too revealing; suffice it to observe that these countries make up over 5 billion of world population, leaving out the approximately one billion who are part of the “high” income developed world. Together, the low and middle income countries generate approximately 6 trillion (2001) dollars of national income, to be contrasted with the 25 trillion generated by high income countries. An index of income that controls for purchasing power would place these latter numbers far closer together (approximately 20 trillion and 26 trillion, according to the World Development Report (2003)) but the per-capita disparities are large and obvious, and to those encoutering them for the first time, still extraordinary.
