Taking out the question on unpaid caregiving will certainly have an impact. Well, I don't know if it will have a direct impact on children, but it will take away some important information that we know affects family income. It affects both children and seniors.
In my work in Toronto, I have a large group of co-workers who provide support services to caregivers of seniors, who are by and large the daughters of older mothers who are caring for their mothers at no cost. Sometimes it's their second or third job, in addition to being a parent to young children and often being in the paid labour force.
So I would say there are many aspects of the impact of taking away the question for tracking unpaid caregiving.
