Quality Information

Data Source

Population projections provide estimates of the size of the future population, and are based on assumptions about births, deaths and migration. The assumptions are based on past trends. 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.

Base population

These National Park Population projections are based on the mid-2006 population estimates for National Parks.
These estimates are available on the following website.
http://www.statistics.gov.uk/statbase/Product.asp?vlnk=15094

Full guidance on the methodology used by the ONS to produce the population estimates can be accessed at:
http://www.statistics.gov.uk/about/methodology_by_theme/sape/default.asp

Revisions

ONS is undertaking a significant programme of work to improve the population and migration statistics it produces. As announced in February 2009, a package of improvements for mid-year population estimates for England and Wales has been identified and these will be implemented in May 2010, when revised population estimates for local authorities in England and Wales for mid-2002 to mid-2008 will be published. Revised population estimates for National Parks will be published later in 2010.

Methodology

These projections are based on the same methodology as the 2006-based Local Authority projections. Detailed information on this methodology is given in the associated technical report:

Welsh Assembly Government | 2006-based Local Authority Population Projections: Technical Report

For the National Park projections, fertility, mortality and migration data was obtained from the Office for National Statistics for the three National Parks and used to form assumptions. The methodology only differed when the required data was not available at a National Park level. The only special population group included in the National Park population projections were the home armed forces.

Frequency
This is the first time this output has been produced. It is expected that National Park population projections will be produced every two years from now on.
