Longitudinal Business Database

The Longitudinal Business Database (LBD) is a large research database containing de-identified microdata about businesses. Data is from a range of Stats NZ surveys and government agencies. Researchers use the LBD for policy evaluation and analysis of business performance. The LBD complements the Integrated Data Infrastructure (IDI), which contains microdata about people and households; the two databases are linked through tax data.
