The 1965 National Fertility Study is the third in a continuing series of major studies of American fertility. Based on interviews with 5,600 married women under the age of 55, the report is concerned with the measurement of all facets of reproductive behavior. Originally published in 1971. 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.
