There is almost a general consensus that underdevelopment in Sudan is associated largely with regional inequality and urban biased
development strategies, which resulted in social conflicts and civil unrest in many parts of the Sudan. The new measurement techniques
proposed by Permanyer (2013) is used to estimate the HDI's, an the Gini coefficient is used to estimate the inequality in human
development between the Sudan states. The results reveal that some states, namely, Khartoum, Northern, Gezira and Nahr Al-Nil have
the highest HDIs, which reflects the concentration of human development programs in these states. On the other hand, Warap, N.B.
Gazal, Lakes, E. Equatoria and Unity are found to have the lowest HDIs. This could be attributed to the lower values of wealth index in
these states. Considering the northern region alone, the lowest values of HDI are found in Blue Nile, West Darfur, Southern Kordofan
and Southern Darfur ( war affected areas since 2002). The Gini Coefficient for the wealth index (0.42) indicate that the significant large
disparities in the distribution of wealth index between Sudan states is the main cause of inequality in human development between the
states of Sudan.
