To understand why people migrate during periods of modernization, Barbara Anderson contends that one must study the place of origin, since the persons at the origin are the potential migrant population. Using data from the 1897 Imperial Russian Census, the author examines two types of migration: that to an already settled, relatively modern area, such as the major cities; and that to a sparsely populated, relatively traditional area, such as the agricultural frontier. Originally published in 1980. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
