Constituency data: household composition, 2021 census

This dashboard has 2021 census data for England and Wales on the number of households in constituencies, as well as the composition of those households. It reflects the population on Census Day, 21 March 2021.

The data shows whether a household is one person, one family, or multiple families and/or individuals who aren’t a family. It also shows whether the household includes dependent children, people aged 66 and over, and married couples.

These figures are provisional estimates created by the Commons Library (see notes, below).

Definitions

A ‘household’ is defined as either one person living alone, or a group of people living at the same address and sharing both cooking facilities and a living room or dining area.

‘Families’ in this data can be:

• Married, civil partnered, or cohabiting couples, with or without children
• A lone parent with children
• Grandparents living with their grandchildren, if the grandchildren’s parents aren’t present.

‘Dependent children’ are those who are either aged 0-15 years or aged 16-18 and in full-time education while living with family. If a 16–18-year-old has a spouse, partner or child living in the household then they aren’t counted as dependent children.

‘Non-dependent children’ are people living with their parents, and are either aged 19 or over, or aged 16-18 and not in full-time education. 16–18-year-olds with a spouse, partner or child in the household are also counted as non-dependent.

The ‘multi-family households’ category includes individual people who aren’t a family but are living together as a household. A group of students in shared private accommodation would count as a multi-family household, for example.

Notes

These figures are provisional estimates created by the Commons Library, which means they are subject to some uncertainty. The Office for National Statistics (ONS) will release final figures for constituencies in 2023 and we will update this dashboard when they become available.

We have constructed these estimates by adding together ONS data for small geographies called Output Areas (OAs). The ONS adjusts the OA figures slightly to protect people’s privacy, so the constituency totals we’ve created aren’t completely accurate. The OAs also don’t precisely match the constituency boundaries, although they are a close approximation.

Data updates

This dashboard uses 2021 census data. The 2021 census is currently the only source of constituency-level data on this topic, which means that there aren’t any updates planned for the near future.
