Figure 2From: Longitudinal variability of time-location/activity patterns of population at different ages: a longitudinal study in California Comparison of time-location/activity data between SUPERB and NHAPS by day-type, gender and age group. The solid bars represent the means and the error bars represent 95% confidence intervals of the means. For NHAPS data, the sample size was 84 for children under 8-year-old, 436 for adults between 26 and 55 years old, and 251 for older adults above 55-year-old. Note that, the people in NHAPS which were compared with "parents of young children" in SUPERB were only in the comparable age group but not necessarily having young children.Back to article page
