Yes This study is from 1990, but I don't think people have physiologically changed much in the last 20 years.
Cost of Care
Nationwide in 2019, the average cost for non-medical home care is $21.00 per hour with the state averages ranging from $16.00 - $28.00 per hour. It should be noted that these are average costs from home care agencies. Private individuals can be retained to provide most of the same services with fees that are 20% - 30% lower. However, independent caregivers are typically uninsured, do not go through background checks and may be unable to provide alternatives in case they are not available to work on short notice. Source
