The purpose of this paper is to present the results of a survival anal
ysis for the duration of particular trip-making activities based on se
x. Specifically, this study investigates the duration of those activit
ies related to household and family support shopping, personal busines
s, and free time and how these durations vary between men and women. I
t was found that there were no significant differences in the survival
curves (i.e., durations) of free-time or personal business activities
; this suggests that men and women spend approximately similar amounts
of time on these activities, although it is not known if the activiti
es themselves are similar (for example, banking versus getting gas). A
lternatively, sex was found to be a very significant indicator of the
duration of household and family support shopping activities, In the m
odel specification, assuming all variables except sex are the same, it
was found that women were 1.32 times more likely than men to spend a
longer period of time in a household and family support shopping activ
ity. Additionally, it was found that women are 1.33 times more likely
than men to have a longer household and family support activity durati
on if the activity is nested in the journey to work trip.
