Explanation of Terms
2001 Survey on Time Use and Leisure Activities
3. Time Use (Questionnaire A)
Daily activities were classified into 20 categories (given in Kind of activities) and surveyed by 15-minutes time slot. The respondents classified and recorded their activities done on the survey date. When the respondent was engaged in more than one activity at the same time, the activity that he/she considered as the main one was reported.
a. Kind of activities
The 20 categories of activities are grouped into three broad areas, called primary, secondary and tertiary activities.
Primary activities refer to those which are physiologically necessary and consist of "sleep", "meals" and "personal care".
Secondary activities comprise those which each person is committed to perform as a member of the family or of the society. Included are "commuting to and from school or work", "work (for pay or profit)", "schoolwork", "housework", "caring or nursing", "child care" and "shopping".
Tertiary activities include all other activities such as "studies and researches", "hobbies and amusements", "sports" and "volunteer and social activities". Time spent in tertiary activities corresponds to what is usually called "free time".
b. Kind of day
The feature of the survey date is classified as follows.
- Day excursion
- Event, wedding or funeral
- Business or training trip
- Under medical treatment
- Holiday or vacation
c. Person(s) being together
Persons being together were recorded in the following classifications by 15-minutes time slot. "Being together" means that the person was so near as to talk with the respondent. The case when there was nobody near whom the respondent knew, or the respondent was asleep, was recorded as "alone".
- With family member(s)
- With classmate(s) or colleague(s)
- With other person(s)
d. Type of average
In regard to time use per day, two types of averages are computed in terms of persons covered; namely "average for all persons" and "average for participants in the activity".
"Average for all persons" is computed by taking all persons as the denominator population regardless of whether or not they reported doing the activity.
To compute the "average for participants in the activity", only the persons who reported doing the activity are included in the denominator population.
In terms of the day of the week, three kinds of averages are computed, namely each day of the week, "weekday" and "weekly average". "Weekly average" is computed as a weighted average of "weekday", "Saturday" and "Sunday".
"Weekly average"= ("weekday average"*5 + "Saturday average" + "Sunday average") / 7
e. Participants in the activity
Number of persons who actually engaged in the activity on the survey date.
f. Participation rate in the activity
(Participants in the activity) / (Total population) * 100 (%)
