Update on release of 2018 Census data
Update on release of 2018 Census data – Media release
10 July 2018
Stats NZ has revised the date for first release of census information from October 2018 to March 2019.
We will confirm the exact response and the coverage rates for the census after we complete our reconciliation processes. Stats NZ’s interim calculations show that full or partial information for at least 90 percent of individuals was received, compared with 94.5 percent for the 2013 Census.
As with previous censuses, we will use statistical methodology to compensate for missing data. For the 2018 Census we are revising this methodology because of the lower-than-expected response. We are discussing this new methodology with our technical customers. We’re also undertaking analysis on how to improve data for small populations, subgroups, and small geographies. The new date for our first release will give us time to develop revised methodology for processing and analysing census data. We are committed to delivering a high-quality and accurate dataset.
There is a long term, international trend of declining census response rates. Because of this we have made a strategic decision to use more administrative data to improve the quality of census data.
Stats NZ is in a good position to adopt this approach as we have been investigating future census models that would supplement census data with administrative data.
