This book, derived from the symposium on “The Demography of Europe” held at the Max Planck Institute for Demographic Research in Rostock, Germany in November 2007 in honor of Professor Jan M. Hoem, brings together leading population researchers in the area of fertility, family, migration, life-expectancy, and mortality. The contributions present key issues of the new demography of Europe and discuss key research advances to understand the continent’s demographic development at the turn of the 21st century.
