The difference will be the biggest in Iran.
Explanation:
The HDI represents the human development index, or rather it takes in account both men and women and creates the statistics as a whole. The GDI, on the other hand is representing the gender gaps between men and women. The GDI is based on the HDI, just that it takes the statistics for the men and women separately and calculates the difference between them.
The measurements are done by taking in account health, living standards, and knowledge. From the countries on the list, the biggest gap between the two will be in Iran. While the HDI will give us some representation for the nation as a whole, and it is not going to be the best, the GDI will show us much different picture. The men rank as big portion of the men in the developing countries across the world. The women on the other hand fall way behind.
The reason for this is the manner in which the country is run. The women don't have the same rights as men. The men actually own their wives and their wives are not allowed to do anything without their permission. The women are almost exclusively allowed to perform only house work, but they are not allowed to work in general, nor they are allowed to educate themselves if their husband, father, or brother thinks it is not the right choice.
