The ACTIVALL file was constructed from the DIARY data to permit easier analysis of all activities recorded during the interviews. The file contains one record for every activity recorded in the diary household member recorded in the grid in Section 1 of the survey questionnaire. It contains multiple records for a particular individual and time slot where more than one activity was recorded for that time slot. It contains at least 48 records for every individual for whom a diary completed, but could - theoretically - include 144 records for a single individual if three activities were recorded for each time slot. It contains two different measures of duration of activity.
The EPISODE file which accumulates consecutive activities into single records. This file contains one record for episode, where an episode is a series of identical activities performed consecutively by a given individual.
This file contains one record for every individual selected to complete a diary. The first selected person in each household has information recorded in section 2 and the second selected person has information recorded in section 4. Information from both these sections is recorded in this file, with the variable Person (PERSON) distinguishing the first and second selected individuals for each household. This file also contains all the information from sections 3 (for the first person) and sections 5 (for the second person) which does not relate to specific timeslots of the diary day.
