A mathematical theory of migration.

Section 1 considers growth of a population; section 2 treats geographical migration by analogy to the flow of heat; section 3 combines sections 1 and 3 and includes immigration; in section 4 are assembled empirical observations taken from the recent United States experience. These are designed to provide a test of the theory.
