AARP has issued a report on the cost of family caregiving across the US, with breakdowns by state. The full report is here: http://assets.aarp.org/rgcenter/ppi/ltc/i51-caregiving.pdf
It confirms what we all knew: about 2/3 of all such care is provided by females, and it is enormous in terms of loss of career and compensation and the caregiver’s own retirement funding.
