^{page 40 note 2} Estimates of area in different sources do not diverge widely. However, population figures, particularly for Saudi Arabia and Yemen, the two most populous countries, vary within a very wide range. The former's population, for instance, was at one time, early in the sixties, estimated by an authoritative but private agency at 3.25 million but by the Saudi authorities at 6 million. Asfour's study for the Economic Research Institute at the American University of Beirut (see later) independently estimated the population at 3.2 million, using an approach different from the ones used in the other estimates. Yemen's population, according to the 3rd edition of the R.I.I.A.'s The Middle East, is ‘certainly 4 and perhaps as much as 8 million strong’ (p. 73). But, in the words of a recent publication, ‘according to reliable estimates the total population numbers approximately 3,500,000 to 4,000,000’ (Manfred, W. Wenner, Modern Yemen 1918–1966, p. 29).Google Scholar The population and area figures for the whole Arabian Peninsula quoted in the text, and as in Table I, are collated from different sources.

^{page 55 note 1} The past development and the prospects of the oil industry are left out of this account, although the oil sector is by far the most significant factor in the economic life of the Peninsula. The exclusion is due to the fact that this sector ought to receive separate treatment. Suffice it to indicate here that the oil-producing parts of the Peninsula produced some 312 million tons of crude oil in 1967 and earned some $1,812 million in direct revenue to governments. The implications of so large a revenue need no emphasis.
