FAQs for our Local Child Poverty Statistics

What does this new child poverty research cover?

This research provides the latest update of child poverty statistics, after housing costs, by locality. This data covers the period of 2022/23. We have produced a figure for child poverty for each Local Authority, and each Parliamentary Constituency. We have provided statistics for the old constituency boundaries, and the new ones which come into use at the General Election 2024.

Which sources of information does this report draw on?

The data in the report is based on calculations that build on the Department for Work and Pensions (DWP) and HMRC Children in Low Income Families dataset, published in March 2024. This DWP dataset estimates the percentage of children living in households with below 60% median income in each local area. These figures draw directly from tax and benefit records. Unlike surveys, they cover the whole population, not just a sample, and can therefore be considered at the very local level.

Using these data, the DWP has produced Before Housing Cost child poverty rates that track changes in child poverty across Britain, at constituency and local authority level, in working and non-working families from 2014/15–2022/23.

The research in this report uses these DWP data alongside information on local rent levels from the Valuation Office Agency and income data from the Understanding Society survey to compile an After Housing Cost set of data.

What is the significance of ‘After Housing Costs’ data?

‘After Housing Costs’ shows the income available to a household once rent, water rates, mortgage interest payments, buildings insurance payments, ground rent and service charges are paid.

This enables a more accurate comparison of what households across the UK have available to spend on food, utilities, clothing and leisure, than looking at income alone, given the disparity of rents in different parts of the UK.

By contrast, a ‘Before Housing Costs’ model takes no account of the fact that, comparing incomes for households in different parts of the country where housing costs vary, does not produce a like-for-like comparison of disposable incomes. As a result, Before Housing Costs figures greatly understate the impact of low income in areas with high housing costs, such as London and Birmingham.

What data did the DWP use to compile Before Housing Cost child poverty data?

The local child poverty estimates compiled by DWP/HMRC are based on family income data.

What does the DWP mean by ‘family’ rather than household?

A ‘family’ is defined as a single person or couple plus any dependent children.

This is not the same as a ‘household’, which also includes people living together and sharing some costs and/or living space, who are not in the same family.

What has the DWP included when defining family income?

In this data, family income is considered using tax, tax credit and benefit data.

What is the definition of a child for the purposes of this data?

This data includes all dependent children aged 0-15, and any children aged of 16-19 who are still in full-time education. The previous means of identifying the child population, Child Benefit, is no longer usable because the exclusion of some well-off families from eligibility for Child Benefit has made it an incomplete count.

What is the measure of poverty used in this data?

A child is deemed to be growing up in poverty if they live in a household whose income is 60% below the contemporary median income.

How much is 60% of median income?

These are calculations of 60% median income (the poverty line) for 2022/23 for types of families, after housing costs. A child is said to be growing up in poverty if their family income is below this poverty line.

• For a family of one adult and one child, 60% of median income, after housing costs in 2022/23 was £255 week
• For a family of one adult and two children, £390 week
• For a family of two adults and one child, £390 week
• For a family of two adults and two children, £530 week

Is this data a measure of absolute or relative poverty?

This data is a measure of relative poverty.

What is the difference between absolute and relative poverty?

The calculation of ‘absolute poverty’ is a measurement of levels of poverty in comparison with median income at a set time in the past. Current absolute poverty measures compare income today with 60% of median income in 2010, uprated by inflation. In other words, they track whether current incomes fall below the poverty level in 2010. As general living standards increase over time, we would expect absolute poverty to fall.

The term ‘absolute’ can be misleading as it wrongly conjures up images of destitution, or not being able to afford basic material essentials such as food, clothing and shelter. Instead, the ‘absolute’ measure used by the government is based on relative income at a fixed point in time.

‘Relative poverty’ can be a more useful measure as it compares a household’s income with the current incomes of other households within the UK. So, rises in relative poverty show that more households are falling below the UK average household income and are not able to meet the financial costs of a basic standard of living. Relative poverty measures give a more accurate picture of what life is like now. In other words, even if your weekly income has not gone down since 2010, it may no longer meet today’s living costs.

If After Housing Cost data is useful, why is this not produced by the DWP at Westminster Constituency and Local Authority level?

There is no way of directly looking at AHC incomes from information held by the tax and benefit authorities, since only some people (notably those claiming Housing Benefit or the rent element of Universal Credit) need to report housing costs.

How have the child poverty statistics changed over time?

Overall child poverty in the UK has increased in the most recent year for which data are available (2022/23). Due to technical issues with this year’s data, we advise against looking at change over time in local areas.

Notes on how the data should be interpreted

The statistics on local child poverty rates after housing costs are calibrated to the Department for Work and Pensions’ (DWP) Households Below Average Income (HBAI) dataset for FYE 2022 and FYE 2023. The DWP’s data has undergone quality assurance, by this department, prior to publication. However, some issues remain, this is partly due to sampling issues related to the Covid-19 pandemic. We advise that users of this data are encouraged to exercise caution when interpreting this. We further recommend that users of these Local Child Poverty Statistics focus on longer-term trends to understand how poverty has changed in an area rather than year-on-year changes which are prone to fluctuations. And avoid comparisons between nations and regions.
