The most comprehensive study of city growth is The Growth of Cities in the 19th Century, by A.F. Weber, vol. xi, Columbia University Studies in History, Economics and Public Law (New York, 1899), pp. 1-478. The meaning of city and urban population is that used by Weber: An agglomerated population of two thousand to ten thousand for towns, more than ten thousand for cities, more than one hundred thousand for great cities. Cf. p. 16.
