Sample description
Country: Bulgaria 2001-02
Study title: Time Use Survey
Collector: National Statistics Institute
When conducted: 15 October 2001 - 15 October 2002
Sampling method and study design: This study was conducted as a part of Bulgarian Population Census Programme to investigate how Bulgarian people use their time. The study largely followed the Guidelines on Harmonized European Time Use Surveys for international compatibility. The data is based on the nationally representative probability sample of the population living in private households in the country regardless of nationality, legal residence status and language. A two-stage cluster sample of 3,132 households was drawn based on the 2001 Census. In each household all individuals aged 10 or over were interviewed using questionnaires. Then, each individual was asked to complete two dairies: one on a weekday and one on a weekend day. Starting at 4.00 AM, each diary was recorded for 24 hours at 10 minute intervals using respondents' own words. Respondents recorded both main activity and secondary activity. In addition, the information on where the activities were carried out, mode of transport, and who else was present (respondents were asked to tick boxes) was collected.
Sample size: 7,787 individuals in 3,132 households were sampled. 3,041 households participated. 7,391 people completed at least one diary. In total, 14,714 diaries were completed.
Response rate: 97.09% of households completed interviews. In 2,653 households all household members aged 10+ completed two diaries, and in 2,913 households, all household members aged 10+ completed at least one diary. At individual level, of 7,787 individuals, 7,391 completed at least one diary (94.91%).
Weighting procedures: Weights adjustment for non-response at the household and at individual level. Diary weights balance the distribution of diaries across the days of the week.
