General description
The Office for National Statistics (ONS) produces national population projections for Wales, and the other UK countries (release date: 30 January 2024). This dataset provides the Wales data from that source by sex, single year of age and each year from the base year of 2021, through the projection period to 2046.Data collection and calculation
The 2021 population estimates have been used as the base for these national projections. The projected population is at 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, which is people changing country of residence for a period of at least 12 months. Short-term migrants (for example, migrant workers) are not counted in the population estimates and hence are not included in the population projections.Data for 2021 and 2022 have not been included in the cube. Users should use official mid-year population estimates for 2021 and 2022. These projections use the latest provisional estimates of international migration, which will be revised as more data becomes available, and assumptions were developed following the latest expert advice.
