The Gazetteer of India on Arunachal Pradesh: Tirap District is very important legal publication by State Government published in 1980. Since this book was published, Tirap District bifurcated to Tirap and Changlang Districts. The two Sub-Divisions namely Changlang and Miao joined to form the current Changlang District.
The Gazetteer mentioned that Changlang Sub-Division had Tangsa and Noctes as the bulk of the population. And Tangsa, Singpho and Yobin inhabited the Miao Sub-Division (Page 2). I got interested to compare how the population had been growing among the Tangsa, Singpho and Yobin as they live closer here in Miao Sub-Division.
|Year of Census||Tangsa||Singpho||Yobin|
A note from the population record between the Census 1971 to Census 2011
· The Tangsa grew almost three times.
· The Singpho rose to five times.
· Yobins to three times of its population in 1971.
