Children living in households with less than 40% median household income after housing costs in New Zealand

Income: This data refers to the equivalised disposable household income. It is the household income divided by a factor that takes into account household size and composition. This is to allow living standards to be compared across households.
DEP-17 score: The DEP-17 index focuses on the low living standards end of the spectrum and includes questions about ‘enforced lack of essentials’, ‘economised, cut back, or delayed purchases a lot’, ‘in arrears more than once in last 12 months’, and ‘financial stress and vulnerability’.

Stats NZ emphasises the need to look at the general trend over time and caution against reaching definitive conclusions from reported year-on-year changes.
Due to its relatively small sample size prior for some years, the underlying data source (i.e. the Household Economic Survey) was not able to deliver robust results when more precision is required in a given year.
The Household Economic Survey tends to have lower response rates from households in low socio-economic areas, which means that these households are often underrepresented in the sample.

After thorough data quality analysis, Stats NZ is confident that the data produced for the year ended June 2024 is fit-for-purpose, within the margins of uncertainty on the estimates.

Data collection for the year ended June 2022 was disrupted due to COVID-19 alert level restrictions, lockdowns, and other disruptions, which resulted in a significantly reduced sample size. Users should note that margins of error are high when using 2022 data.

Child poverty statistics provide estimates of low income and material hardship rates for measures listed in the Child Poverty Reduction Act 2018.

Statistics in this release are used as baseline rates by Government to set 3- and 10-year targets for reducing child poverty for the three primary measures specified in the Child Poverty Reduction Act 2018.

These statistics are based on the household economic survey (HES). This survey had a target sample size of 20,000 households, and an achieved sample size of approximately 19,100 households for the year ended June 2024.
