Four example daily activity classifications identified from the American Time Use Survey. The vertical axis represents the relative proportion of each activity type, where each subplot is representative of a cohort of respondents from the ATUS who have similar patterns of activity as identified by our classification model. Class A represents the day of a typical working-class adult. It begins with sleeping, transitions into work, then recreation, and ends with sleep. Class B represents a day that primarily consists of recreation, whereas Class C represents a day that primarily consists of household care, which can include child care. Class D is similar to Class A, but consists of swing or night shift workers; this demonstrates that the classifier can differentiate both conceptual and temporal groupings of activities.
