For the ethnic population - "This figure only includes the Pumi living in Yunnan Province. Due to historical reasons, Pumi living in Sichuan Province are all included in the Tibetan ethnicity. It is therefore difficult to establish a precise figure and several estimates have been made: Steven Harrell (2001) mentions 31000; Lu Shaozun (2001:1) mentions around 50000 Pumi-speaking Tibetan, of which around 34000 live in Muli Tibetan Autonomous County."
