National Statistical

The Office for National Statistics produces subnational population projections (SNPPs) to give users an indication of the potential future population size of English local authorities and health geographies. Today we’ve released our 2022-based SNPPs which will be widely used in planning, for example, health, education and housing. We don’t know exactly what will happen in a local area in 10- or 20-years’ time, so offer a range of scenarios, or variants, so decision makers can use the right projection for their needs. In today’s bulletin, we focus on the ‘migration category variant’. James Robards explains what this is and why we’re using this approach.
