Profound changes have occurred in the demography and sociology of Italian fertility since Napoleonic times. Using the statistical system instituted in 1861 with national unification, Massimo Livi-Bacci provides a systematic and detailed analysis of fertility trends in Italy in the nineteenth and twentieth centuries. He brings to light the main features of the secular decline: its rapid occurrence in the northern and central areas; the widening urban-rural gap; the shaping of social and economic differences; and the late, slow downward trend in the South. Multivariate statistical analysis enables the author to measure the changing relationship between fertility and social or economic phenomena. Historical evidence illustrates the effect on fertility of mass emigration and Fascist policy as well as of social changes such as those in agrarian structure, mobility, and communications. An altered attitude toward procreation is evident in some parts of Italy in the early nineteenth century. The decline becomes apparent in certain northern and central regions in the 1870s and 1880s and it appears at the aggregate national level in the 1890s. Originally published in 1977. 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.
