This volume is an important study in demographic history. Garrett, Reid, Sch?rer and Szreter use techniques and approaches drawn from demography, history and geography to explore the conditions under which declines in both infant mortality and fertility within marriage occurred in England and Wales between 1891 and 1911. Extensive use is made of previously unavailable census data drawn from thirteen communities in England and Wales, particularly those from the 1911 "fertility" census. The book's sometimes surprising conclusions will be of interest to all historians of Britain and of demography.
