Today we’re publishing the first data from our investigation of the net worth module attached to the 2017-18 Household Economic Survey. This data looks at wealth broken down by five groups: the Poorest 50% (P1-50), the Next 40% (P51-90), the Next 5% (P91-95), the Next 4% (P96-99) and the Wealthiest 1% (P99-100). The data are available here. They’re also discussed in this Guardian piece. Thanks to Statistics New Zealand for the collaboration that has enabled this data to be released.
The results in this spreadsheet are not official statistics; they have been created for research purposes from the Integrated Data Infrastructure (IDI) managed by Statistics New Zealand. The opinions, findings, recommendations and conclusions expressed in this article are those of the authors not Statistics NZ. Access to the anonymised data used in this study was provided by Statistics NZ in accordance with security and confidentiality provisions of the Statistics Act 1975. Only people authorised by the Statistics Act 1975 are allowed to see data about a particular person, household, business or organisation, and the results in this table have been confidentialised to protect these groups from identification. Careful consideration has been given to the privacy, security and confidentiality issues associated with using administrative and survey data in the IDI.
