Kaman are now 50k out of 4 million resident in Arakan. 1 out of 80 people in Arakan are Kaman. And you are saying they were 1 in 3 in 200 years ago? What is the reason for this drastic reduction of population? Did most of the Kaman converted to Rohingya?not rohingya. its kaman people who already recognized as ethnic people of Myanmar.
Read the entire report. It said the people Mohamedan speak Indic or hindustani. Your so called Kaman speak burmese and actually those who inter married with burmese population over time. Most kaman what you trying to get out of are actually Bengalis. 20% of current Bangladeshi are actually the descendant of what you call Kaman.not rohingya. its kaman people who already recognized as ethnic people of Myanmar.
