Please note that household projections show the number of households there would be in the future under a set of assumptions. The similarities between the methodologies mean that it is possible to broadly compare the results for the four countries. Although users should be aware that any differences may be partly because of the different methods used to produce the projection results. for more details please see ONS's comparability note: https://www.ons.gov.uk/peoplepopulationandcommunity/populationandmigration/populationprojections/methodologies/householdprojectionsacrosstheukuserguide#comparability-summary

Household projections show the number of households there would be in the future if a set of assumptions about the size and structure of the population and that population’s patterns of household formation were realised in practice.

The projections generally do not take into account any policy changes that have not yet occurred, nor those that have not yet had an impact on observed trends.                  

England: Data taken from the 2016 - based household projections.

Wales: Data are 2014 - based household projections.

Scotland: Data are  2016 - based household projections.

Northern Ireland: Data are taken from the 2016 - based household projections.

Data for UK is presented by adding up the data from the constituent countries. These data are a combination of rounded and unrounded figures.
