As the demand increases for statistics and data to measure the impact of the COVID-19 pandemic, we have had to change our data gathering and release practices, focussing efforts on priority analysis and statistics.

General description
This dataset provides household projections for National Park authorities in Wales by household type from the base year of 2014, through the projection period to 2039.

Note that the projections become increasingly uncertain the further we try to look into the future.

Data collection and calculation
Data are calculated using a methodology which uses the 2014 to 2039 population projections data published previously along with information on household structure from the 2011 Census. For more information on the methodology, please see the statistical release in weblinks.

The methodology was developed in conjunction with the Wales Sub-National Projections (WASP) Working Group. Members of WASP include representatives with experience of demographic and housing data from Welsh local authorities, the Local Government Data Unit and the Welsh Government.

Projections only indicate what may happen should the recent trends continue. Projections done in this way do not make allowances for the effects of local or central government policies on future population levels, distribution and change. They are merely an indication of what would happen if certain assumptions were realised.

Frequency of publication
Every three years

Data reference periods
Data are published for the period 2014 to 2039.

Users, uses and context
See the statistical release in weblinks.

Rounding applied
Data are rounded independently to the nearest whole number and may not add exactly.
