Each year the mass media and many governments look keenly at the country rankings by the Human Development Index (HDI). In the 2010 Human Development Report, Zimbabwe has the lowest HDI in the world at 0.14 on a (0,1) scale (UNDP, 2010). The next lowest is the Democratic Republic of the Congo (DRC), with 0.24. (Norway is highest, at 0.94.)
It is natural to ask: what would Zimbabwe need to do to get its HDI up to the level of the DRC or better? Zimbabweans will no doubt have a strong interest in knowing the answer, as will those interested in the HDI in general.
