Britain should build "new community institutions" specifically designed to help elderly people live independent lives to cope with the looming care crisis.
IPPR senior research fellow Clare McNeil said:
The supply of unpaid care to older people with support needs by their adult children will not keep pace with future demand.
Thousands of people in their 60s and 70s today could be left to cope on their own when they need care in the future, with overstretched services unable to make up the shortfall.
Britain needs to build new community institutions capable of sustaining us through the changes ahead and to adapt the social structures already in place, such as family and care, public services, the workplace and neighbourhoods.
