UNSCOP report (A/364), 3 September 1947
"The semi-desert Beersheba area in the south has at present a settled population of 7,000 (mostly in the town of Beersheba) and about 90,000 nomadic Bedouins." [...] In addition there will be in the Jewish State about 90,000 Bedouins, cultivators and stock owners who seek grazing further afield in dry seasons. [...]
Note 42 bij CHAPTER II, par. 12: "The 1931 census revealed that there were 66,000 nomadic Bedouins; today they are estimated to number 90,000. Little is known demographically about the people and no account is taken of them in the statistics of this chapter, which deal only with the settled population."
