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.

Well-being in New Zealand is generally high, although there is room for improvement in incomes, housing affordability, distribution, water quality and GHG emissions. Economic growth is projected to remain around 21⁄2 per cent. The main risks to the outlook are rising trade restrictions and a housing market correction. Labour market reforms have been initiated to increase wages for the low paid but will need to be implemented cautiously to minimise potential adverse effects. Substantial planned increases in bank capital requirements should reduce the expected costs of financial crises but might reduce economic activity.
What drives economic growth in New Zealand? How has New Zealand been impacted by globalization and the financial crisis? What will shape future productivity and competitiveness? In this book, leading economists assemble key data to provide an analytical introduction to the contemporary New Zealand economy. Interpreting key economic indicators over time—gross domestic product and interest rates, population, employment and productivity levels, trade and investment, and government accounts—this examination focuses particularly on two issues: globalization and the rise of the Asian economies during the past 30 years, and the origins and continuing effects of the 2007&–08 global financial crisis. Rich with local data and case studies, this is a clear and concise assessment of the current structure and performance of New Zealand's economy from a historical and global perspective.
