9 The further changes revealed by the 1980 census have not yet been fully discussed, but preliminary analysis demonstrates that migration to the southern and western states is continuing; see: Hauser, Philip M., “The Census of 1980,” Scientific American, 245, 5 (11 1981), 53–61.CrossRefGoogle Scholar
10 Dates of admission to the Union, and areas of the states for calculating population densities, are in the American Heritage Dictionary (1969). Agricultural statistics in Historical Statistics, 1, 457, 460, 500, 510, when plotted arithmetically, show that Malthus inferred correctly that the food supply, however it is, or can be, measured, tends to increase arithmetically. Other typical confirmations include the graphs in Jensen, Neal F., “Limits to Growth in World Food Production,” Science, 201 (1978), 317–20CrossRefGoogle ScholarPubMed, and Barr, Terry N., “The World Food Situation and Global Grain Prospects,” Science, 214 (1981), 1087–95CrossRefGoogle ScholarPubMed, at least when allowances are made for improvements in agricultural technologies and for weather conditions unfavorable to food growth. Petersen (Malthus, [see n. 5], 61 is certainly correct in inferring that Malthus drew upon his training in mathematics to arrive at his famous contrast of the growth atterns of population and of food supply, not upon actual numerical data.
