Wales has an increasingly ageing population and the question of how to fund social care for the elderly is the focus of an independent report out today.
It says spending per head of the population aged over 65 has been declining. That may be because of a squeeze on local authority budgets and it could mean that demand for care is not being met.
The study says the problem is only going to get worse with the population aged over 65, and especially people over 70 increasing in absolute terms and as a proportion of the population over the next two decades.
The report's author, Prof Gerald Holtham, says one solution could be a tax increase of between 1% and 3% with the latter being paid by those over 60.
The economist, who is a former adviser to the Welsh Government, said setting up a social care fund could meet the rising costs of elderly care and also provide investment of several hundred million pounds to the Welsh economy.
Responding to the report, the Welsh Government say they are continuing to examine options for funding of social care.
