I would harbour a guess that the vast majority of the older population would want to stay in their own homes. Given the lack of suitable alternative accommodation like retirement villages etc it's a non runner for years to come. Some housing associations like Cluid offer sheltered or assisted-living type accommodation to the elderly who are without homes of their own and to those with long term disabilities etc. For the rest of us who do own our own homes and may want to downsize at some time, unfortunately we are a long way off the Californian type independent living model of elder care.
