An authoritative demographic history of the New Zealand family from 1840&–2005, this reference is a collection of statistics that interprets the changing role of the family and its members. Using detailed research spanning 165 years, the authors chart the move from the large family of the 19th century to the baby boom, the increase in family diversity, and the modern trend towards unsustainably small families. This analysis of society helps trace changing attitudes and the structure of society by noting the reasons for and consequences of the demographic changes.
