17356 Yaka 10000-99999 "The generally accepted population figure for the Bayaka people is around 30,000 (Bahuchet and Thomas 1986:81, Bahuchet 1993b:81, Grimes 2000). It is very difficult to determine the exact size of the Bayaka population due to their mobile hunter-gatherer lifestyle. The Central African government census of 1990 registered about 9,400 Bayaka in C.A.R (Recensement RCA 1988). Previously, Cavalli-Sforza had attempted a limited survey of the Bayaka of the Lobaye. He noted that only the Bayaka who happened to be near a village at the time of the census would be counted (1986:26). This same restriction would certainly hold true for the 1990 government census."
