21 November - 17 December 2005
Sampling method and study design: This study builds on lessons for collecting national time use data from the UK HETUS study in 2000-2001. The time diary was one element of the Omnibus surveys conducted over four seasons of 2005. An independent cross-sectional multi-stage stratified random sample of private households in Great Britain (England, Wales and Scotland) is drawn for each month of the Omnibus survey, and the diary served as the module accompanying the core of basic survey details collected with every Omnibus survey. One person aged 16 or older was selected for the interview and the diary. Interviewers met respondents face to face, and assisted in the collection of one-day light diaries with 30 precoded activities, plus location (home or elsewhere), mode of transport (car/van, walk/jog, pedal bicycle, bus/coach, train/underground, and other) and travel purpose (escort, shopping, paid work, purely for the enjoyment of travel, and other reasons). Though the diary includes 10 minute time slots, interviewers were prompted to ask respondents about any activity which they undertook that lasted 5 minutes or longer. The interviewer collected both main and secondary activities. Main activities are marked with a "x" and the beginning and end of the time the activity lasted; secondary activities are marked with a "0" at the beginning and the end of the activity. The diary day began at 4AM on the previous day, and ended at 4AM on the morning of the interview. Interviewers had specific instructions to prompt respondents to give an account of the full 24 hours, to have only one main activity at a time and no more than one secondary activity, to record location and mode/purpose of transport, to ask when telephone conversations took place, to ask when the diarist used a computer, and to ask whether the diarist had a child in her or his care during the day. Interviewers were instructed to record child care over any other secondary activity. Travel as part of paid work (such as driving a bus) is not recorded as travel, though travel to a work meeting during work time is recorded as travel
Sample size: March-April: 1651 diaries; June-July: 1188 diaries; September-October: 1117 diaries; November-December: 985 diaries; Total: 4941 diaries
Response rate: Across the four waves 59% returned diaries
Weighting procedures: The weights adjust for the unequal probability of an individual being selected from the number of people aged 16 or more in each sampled household and also balance the distribution of the days of the week. The weights from each of the four survey periods are summed and then divided by 4
