Miroslav Macura, a scientific collaborator with the Faculty of Social Sciences at the University of Geneva, reviews The Global Spread of Fertility Decline: Population, Fear and Uncertainty. The book examines population trends, which have dropped in developed countries over the past four decades. Drops in fertility have been recorded in developing countries, including China and Brazil, as well, and the authors examine the global phenomenon of low fertility. The authors argue that risks faced by individuals and couples in childbearing years, including family breakup through divorce, loss of income and erosion of entitlements, have contributed to the drop in fertility. In examining the rise of immigrant populations, the authors look at Islamic migration to Europe and Mexican migration to the US.
