This report updates the estimate of the value of unpaid care published by Carers UK in 2002 in ‘Without Us…? Calculating the value of carers’ support’. Based on data available for the first time at local as well as at national level, and on comprehensive information about the time carers devote to supporting those who need their help, the report reveals just how crucial carers are to the health and social care system and to the UK’s economy.
