Figure 24: Annual growth rate in HDI of OIC Member States by income groups between 1990

and 2017

Source : Own calculations from UNDP (2018)

Note: The rates are calculated as the annual compound growth rate.

Although the HDI value increases with income, the association between income and HDI rank is

more ambiguous at the country level for the given income groups. The last column of

Table 5

includes the difference between HDI rank and gross national income (GNI) rank for different

income groups. This difference is -6.1 on average for OIC implying that human development lags

behind the economic prosperity in the OIC member states in general. This difference is much

smaller for low and lower-middle income countries (2.1 and 0.6 respectively). However, it is

considerable higher for upper-middle income and high income countries. The difference for high

income group is almost -30 implying that this group was not able to translate its wealth into

human development as much as the other high income countries.
