Note that the 15-20% of people who are "disabled" are not defined as needing around-the-clock caregivers. Disability is a spectrum.

I would indeed dismiss that particular statistic about the number of kids spending 50+ hours looking after family members, because it is likely wrong by an order of magnitude.

Also that doesn't mean that 15-20% of people of parenting age are disabled. It might skew elderly.
