General description
This dataset provides population projections for National Parks and Residual Local Authority Areas in Wales by gender, single year of age and each year 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
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.

The 2014 population estimates have been used as the base for the National Park projections. The projected population is for 30 June each year. The base population estimates are based on the usually resident population. Usual residents away from home temporarily are included, but visitors are excluded. Students are counted at their term-time address. It should also be noted that the UN definition of an international migrant is used - those changing country of residence for a period of at least 12 months. Short-term migrants (eg migrant workers from Eastern European countries) are not counted in the population estimates and hence are not included in the population projections.

These projections are based on a similar methodology to the 2014-based local authority population projections. Detailed information on this methodology can be found via the weblinks. 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 of publication
Every three years

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

Users, uses and context
See the National Park authority population projection statistical release in weblinks.

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

Revisions information
No revisions have been made to the data published for 2014. These data replaced the 2013 national park projections for Wales as the formal estimates of population growth.
