It's just that it is the only question providing us with statistics on unpaid work. Question 33 should be called “Household Work” from now on instead of “Household Activities”.
Someone used the expression “go walking” earlier, but, if that means getting a sick person some fresh air and, by doing so, helping them on a psychological level, it is still work. Many aspects of this responsibility are work. But it is not recognized as such, and as long as that's the case, similar paid work will be affected. If we recognize that work being done at home is in fact work, we could agree to pay or recognize domestic employees more. We will increasingly recognize the work of people working in daycares and the work of everyone doing what a good mother should do at home by taking good care of her children.
