2.2.1. Trends in OIC
Figure 23 shows the evolution of HDI for OIC member states in different income groups between
1990 and 2017. It reveals that there is an improvement for each income group in the defined
period. It also clearly shows that the HDI values are strongly associated with income level. The
HDI values consistently increases as income group rises. High income and upper-middle income
countries exhibit HDI trends that are over the OIC average and the lower-middle and low income
countries have lower HDI values compared the OIC average.

Note: The averages are unweighted. That is, each country in the groups has the same weight irrespective of its
population.
Figure 24 reveals that there is a sign of convergence. Low income countries grew at much higher
rates than other income groups over the period. The growth rate of low income group was nearly
3 times higher than that of high income countries and nearly two times higher than upper middle
income group. Another important improvement to note is that the high income group exhibits a
higher level of annual growth compared to OECD average.
