time use registration goals hetus project
Time-use registrationGoals HETUS-project
  • Since Szalai a number of conventions with regard to the methodology of time budget research have been established
  • Nevertheless: a great variety of recording methods at the moment of recording the information still exists
    • Fixed / open time interval
    • Precoded activity list / after coding
    • Number of diary days recorded
  • HETUS: one general guideline for all member countries

=> Guidelines for recording the time-use information

European Conference on Quality in Official Statistics, 8-11 July 2008, Rome

time use registration goals hetus project1
Time-use registrationGoals HETUS-project
  • Collecting time-use information in a comparable way

=> Harmonisation

  • To make comparisons between countries possible
  • Major concerns
    • Design of the diary
    • Field work
  • Our interest centres on the recommendation regarding the number of diary days

European Conference on Quality in Official Statistics, 8-11 July 2008, Rome

time use registration recommendations to the number of diary days
Time-use registrationRecommendations to the number of diary days
  • It is recommended to use two diary days, i.e. one weekday (Monday-Friday) and one weekend-day (Saturday and Sunday)
  • It is strongly recommended that diary days/dates be allocated to households/individuals by a controlled random procedure
  • It is recommended that the survey days/dates are representative of, and cover a full 12 month period

time use registration presenting the time use results
Time-use registrationPresenting the time-use results
  • Calculating estimates for:
    • Weekdays (Monday-Friday)
    • Saturday
    • Sunday
    • All days of the week (Monday-Sunday)
  • Synthetic workweek: weekday*5
  • Synthetic weekend: weekend day*2
  • Synthetic week: (weekday*5)+(weekend day*2)

time use registration goal this presentation
Time-use registrationGoal this presentation
  • Rationale for 2 vs. 7 days:
  • Costs of fieldwork
  • Response rate
  • Learning/boredom
  • Number of respondents
  • Zero observations
  • Intra-personal variability
  • More statistical options
  • Testing the consequences of the recommendation of recording only 2 days instead of 7 consecutive days

European Conference on Quality in Official Statistics, 8-11 July 2008, Rome

time use registration daily vs weekly cycles an example
Time-use registrationDaily vs weekly cycles: an example
  • The week cycle is an important cycle in our social life
    • F.e. working time, work during weekdays, week/weekend contrast, the specific character of Sunday and Saturday in the weekcycle
  • Certain activities follow a weekcycle and occur once or several times a week
    • F.e. sports, social life, taking part in associations, cleaning, …

time use registration data used
Time-use registrationData used
  • Flemish time budget dataset
  • Respondents filled in 7 consecutive days, starting day was randomly determined
  • Pooled dataset
    • 1999 in total 1394 respondents
    • 2004 in total 1860 respondents
  • Open time interval / precoded activity list

European Conference on Quality in Official Statistics, 8-11 July 2008, Rome

time use registration creating 2 day dataset
Time-use registrationCreating 2 day dataset
  • Selection of 2 days with the guidelines of EUROSTAT in mind
  • Selection of the weekday (total, n=3.254) was not random

=> We selected the first registration day if it was a weekday

=> If not, randomly selected one weekday

  • Selection of Saturday or Sunday (total, n=3.254) was random
  • Weighting
    • Socio-demographic (sexe, age & education)
    • Diary days (Mon=Tue=Wed=Thu=Fri); (Sat=Sun)

time use registration results in words
Time-use registrationResults in words
  • The estimates on population level between 2-day and 7-day registration for a synthetic week are comparable
  • Positive and negative factors (methodology & quality) keep each other in balance
  • The largest difference is 18 minutes for the activity ‘Sleep & rest’, however as a percentage of the total time spent sleeping and resting it is nearly 0
  • Essential conditions:
    • Large(r) sample
    • With respect to the length of the registration period
    • Equal dispersion of the diary days

Time-use registrationResults in words
  • Due to a lower sample size, the results are less stable
  • Individual diary days are represented by a smaller number of respondents
  • Some activity groups are less biased, there is an indication that ‘the more a (sub-) population takes part in an activity as a group, the less a large sample size is needed for a good estimation.’
  • Socio-demographical variables / breakdowns to:
    • Sexe / age / education / …
    • Sexe x age / …
  • Closer look with other (international) data -> lager sample

European Conference on Quality in Official Statistics, 8-11 July 2008, Rome

time use registration variation in different days of the week
Time-use registrationVariation in different days of the week
  • Kalton (1985) variability across the weekdays, Monday till Friday is relatively small
  • Stinson (2000) finds evidence that the activity pattern of Friday is different from the other weekdays, and also from Saturday and Sunday

And, could change even more in the future

  • Szalai T-Test
  • Results pooled dataset

time use registration participation rate
Time-use registrationParticipation rate
  • Time-use accounting identity

=> Ti=PiT’i

Ti = mean time population; Pi = population participation rate; T’i = mean time participants

  • Participation rate per day, or average along longer period

HETUS

Pi(weekday)=(Pi(mon)+Pi(thu)+Pi(wed)+Pi(thu)+Pi(Fri))/5

  • Participation rate across f.e. weekday

7-day registration

Pi(weekday)=Pi(Mon thru Fri)

  • F.e. trafic gestion

time use registration conclusions
Time-use registrationConclusions
  • Weekcycle is an important rhythm is our society
  • Estimations on population level for a synthetic week on basis of a 2-day registration is comparable with a 7-day registration, the sample size is nevertheless an important factor
  • Participation rate and mean time per participants can not be calculated for a weekcycle
  • To understand individual behaviour it is appropriate to collect information over 7 consecutive days
  • The actual length of the diary period relies on the purpose of the research

European Conference on Quality in Official Statistics, 8-11 July 2008, Rome

time use registration future tasks
Time-use registrationFuture tasks
  • Try to find a method / circumstances to extrapolate participation rates
  • Make comparisons with international datasets with a larger sample size to test our findings and broaden our recommendations
