The aim of the paper Options for meeting longitudinal information needs: A preliminary investigation is to identify the main future requirements for longitudinal data for research and policy purposes, and to discuss how well existing data sources could meet these requirements, as well as options for addressing the gaps. Our focus is on longitudinal information needs relating to individuals, families, and households. Information needs relating to businesses are outside the scope of this paper.
Two further papers came from this: Meeting longitudinal information needs: Recommendations for Statistics New Zealand and Statistics New Zealand's response to recommendations for meeting longitudinal information needs.
