Household estimates

Annual household estimates for local authorities in Wales are produced by the Welsh Government.

Household estimates are produced by making assumptions about household size and composition and applying these assumptions to population estimates. They are important for the public sector and other users who need to consider recent trends in housing demand - in order to plan for the future, provide housing and deliver services. The estimates are also used to calculate rates and other statistics, and are available by household type in terms of numbers of adults/children.
