Figure 1

Pie chart showing the mean percentage of time the NHAPS respondents spent in six different locations on the diary day (weighted). Time spent indoors (composed of time in a residence, in an office or factory, in a bar or restaurant, or in some other indoor location) is represented by lightly shaded slices. The percentages in the figure are the mean percentages taken over individual percentages for people in the NHAPS sample. Individual percentages were calculated from the time spent in each location over the total amount of time spent, which was equal to 24 h (1440 min) for each individual (see Table 6 for the number of doers for each location).
