Microdata refers to unit record and aggregate data that cannot be made publicly available, unless data is modified to protect respondent confidentiality. Microdata can be collected through surveys, censuses or administrative processes.
Statistics New Zealand's microdata access services provide researchers with high quality statistical data on which to base their analyses. This reduces the cost of research and helps avoid the creation of duplicate data collections..
Access to microdata is carefully controlled to ensure that data is not misused. Further information on the security and confidentiality of data and other factors that influence the nature of microdata access at Statistics New Zealand are detailed in the Microdata access policy.
Microdata services
Data Lab
The Data Lab provides secure computer facilities in Statistics NZ's offices where researchers can work with anonymised microdata. Strict eligibility criteria apply.
Confidentialised Unit Record Files (CURFs)
CURFs are unit record data that have been modified to protect the confidentiality of respondents' while also maintaining the integrity of the data.
Basic CURFs are made available on a CD-ROM. More detailed CURFs, known as expanded CURFs, will be made available through the AtoM service.
Access to Microdata (AtoM) Service
The AtoM service allows researchers to submit SAS code, through the AtoM website, to run against selected Statistics New Zealand datasets. The output of the SAS code is confidentialised and made available to the researcher on the AtoM website.
