POPULATION 69 America, it may be taken as over 26 per cent. Obviously something like 15 per cent. is probably too high an estimate of the possible total. Accepting it, the 52-5 million square miles of entire surface become reduced to 7-875 of available surface, that is, 5040 million acres. It can hardly be assumed as probable that this area can be made to produce more than the equivalent to the average of, say, 14 bushels of wheat per acre. This at the outside, accepting an annual average require- ment of, say, 473 lbs. per person as probably fairly correct, would make provision for, say, 1-776 persons, hence the possible population would be 5og40—see above—multiplied by 1-776, that is, say, 8950 millions, an estimate which is almost identical with one obtained a little earlier. The several figures thus far obtained in this review of the possible population of the earth, expressed in millions, are then as follows: 13,440," 4200, 3552, 5650, 17,642,% 5645, 8978, 8400 and 8950, of which the two largest—marked with asterisks were recognised as not really possible estimates. The mean of the seven others is 6482 millions. We do not submit this as in any way representing the probable limit. Tt has already been indicated that, neglecting the vicissitudes of Nature, “the greatest possible popula- tion ” is a function of such things as (2) the efficiency of human organisation, (5) the appropriate localisation of human beings upon the earth, (¢) the standard-of- living adopted, and (4) the degree of freedom of migration attained, for the purpose of permitting any degree of concentration reached in any region to be adjusted to the local population-capacity of other regions. It may again be remarked in this connec- tion, that even differences in language impose real difficulties in making the earth’s inhabitants the largest number possible, and because of this it is not
