The result of all those factors, is that the Armenian population censuses, according to the specialists that criticize them, is an important under counting of the Armenian population, that could have gone as far as misrepresenting it by half. Lynch critic itself regarding the inclusion of all the Muslims together, when there were probably Armenians in the count, is supported by the Ottoman census, that contain an anomaly that in some region like Van, the Muslim population from one census to another jumped to about 50%, suggesting that numbers for the Ottoman government could have been used as political tool, and went as far as transferring Armenians in the table as Muslim. In fact Ottoman census didn't define any ethnic groups, only religious ones. In this context Armenian meant an adherent of Armenian Apostolic Church not an ethnic Armenian. Ethnic Armenians who claimed to be Muslims were counted as Muslims, Armenian Protestants were counted as others. So Ottoman records aren't reliable sources- the problem is that they don't give the ethnic breakup of the population, only the religious one. The fact that the 1912 records are based on a census that was conducted under the Hamidian regime, according to the critics, makes it dubious. Turkish records as also suggest that sultan Hamid might have intentionally under-counted the Armenian population. The Turkish author Kâzım Kadri writes, “During the reign of Abdul Hamid we lowered the population figures of the Armenians...” He adds, “By the order of Abdul Hamid the number of the Armenians deliberately had been put in low figures.”
