"25 Muslim Majority Countries have Achieved Average Literacy above 90%"

So whats holding Muslims back?

According to the survey by John Miller, 5 Muslim countries namely Azerbaijan, Tajikistan, Kazakhstan, Turkmenistan and Uzbekistan  find places amongst 25 countries with highest literacy rates of 100%.World Bank and UNSECO data for 2018 shows that  25 Muslim Majority countries have achieved  average literacy above 90 per cent. These include Saudi Arabia (95%), Indonesia(94%), Malaysia(94%), Iran(90%), Jordan(96%), U.A.E.(94%) and  Turkey (95%). Nine countries,  including  Syria (86%), Tunisia (82 %), Iraq (79%), Egypt (75%) Algeria (73) are and Morocco (72%) were reported to be in the bracket of 70% to 89%. Unfortunately fifteen countries including largely populated countries of Bangladesh, Pakistan and Nigeria still lag behind in literacy (Less than 62%). However, compared to the literacy Data of 1980 (Av. 30%), 2018 data is highly satisfactory. Global literacy rate (2017) is 82% (Men, 87%; Women  77%).¹

So then what exactly is holdling Muslim populations back from advancing?
