The UK population is ageing. By 2040, nearly one in seven people is projected to be aged over 75 and in some areas of England, this age-group will make up over 25% of the local population. Concerningly, unless we take action, many of these people will live years of their later lives in poor health. This has huge implications not only for health and social care but also for how we plan, create and manage homes, streets, neighbourhoods and places to support healthy ageing.
