Household Labour Force Survey

Methodology Type of data: Survey Data collector: Statistics NZ’s business unit Integrated Data Collection (IDC) performs the data capture. Mode of data collection: The HLFS uses three modes of collection: a computer-assisted personal interview (CAPI), a computer-assisted telephone interview (CATI), and a self-complete questionnaire. The first interview is always a CAPI interview. Frequency of data collection: Quarterly Quality information Editing: none. Missing data: We impute for sex, age, and full-time/part-time status if these are missing when we finalise the weekly data into table of imputation and post stratification (TBLIMPPS) Other quality issues: We adjust for non-response and then calibrates to age and benchmarks from demography. The benchmarks used are five-year age groups by sex, and the number of Māori adults by two age groups (aged 15–29, 30+). Privacy issues exist around the name and location of individuals. The HLFS table that is accessible to researchers do not contain any name or address information to identify an individual. All researchers who have access to HLFS data have had their research proposals assessed using Statistics NZ’s microdata access protocols and only approved researchers who have been granted access by Statistics NZ may view the HLFS data.
