=====Complexity=====
A third problem is the complexity of domestic labor and the issues of separating unpaid work categories. Time use studies now take multitasking issues into account, separating primary and secondary activities. However, not all studies do this, and even those that do may not take into account "the fact that frequently several tasks are done simultaneously, that tasks overlap, and that the boundaries between work and relationships are often unclear. How does a woman determine her primary activity when she is preparing dinner while putting the laundry away, making coffee for her spouse, having coffee and chatting with him, and attending to the children?"<ref name=Luxton /> Some activities may not even be considered work, such as playing with a child (this has been categorized as developmental care work) and so may not be included in a study's responses.<ref name=Luxton /> As mentioned above, child supervision (indirect care work) may not be construed as an activity at all, which 
"suggests that activity-based surveys should be supplemented by more stylized questions regarding care responsibilities" as otherwise such activities can be undercounted.<ref name=Folbre /> In the past, time use studies tended to measure only primary activities, and "respondents doing two or more things at once were asked to indicate which was the more important." This has been changing in more recent years.<ref name=Luxton />
