Household projections provide estimates of the number of households and household types for national parks.

These projections provide an indication of the future number of households and their composition in the national parks’ for the period 2018 to 2043.

The projections are not forecasts. They do not attempt to predict the impact of government policies, changing economic circumstances or other factors (like the coronavirus pandemic) on future household population.

Main points for 2018 to 2028

Projected change in number of households

  • The numbers of households in all three national parks are projected to increase by 2028.
  • The numbers of households are projected to increase by 4.8% (almost 730) in the Brecon Beacons, 5.3% (550(r)) in Pembrokeshire Coast and by 0.3% (40) in Snowdonia.
  • One-person households and two-person households with no children are projected to continue being the most common household type for all three national parks.
