Thomas Malthus：An Essay on the Principle of Population, Excerpt 72

The consequence of these favourable circumstances united was a rapidity of increase probably without parallel in history. Throughout all the northern colonies, the population was found to double itself in twenty-five years. The original number of persons who had settled in the four provinces of new England in 1643 was 21,200.(I take these figures from Dr Price's two volumes of Observations; not having Dr Styles' pamphlet, from which he quotes, by me.) Afterwards, it is supposed that more left them than went to them. In the year 1760, they were increased to half a million. They had therefore all along doubled their own number in twenty-five years. In New Jersey the period of doubling appeared to be twenty-two years; and in Rhode island still less. In the back settlements, where the inhabitants applied themselves solely to agriculture, and luxury was not known, they were found to double their own number in fifteen years, a most extraordinary instance of increase. Along the sea coast, which would naturally be first inhabited, the period of doubling was about thirty-five years; and in some of the maritime towns, the population was absolutely at a stand.
