This chapter explores the data from the time use module of the Tanzanian Integrated Labour Force Survey (ILFS) carried out by the National Bureau of Statistics in 2006. The 2006 time use module of the ILFS represented the fi rst time that the National Bureau of Statistics had attempted this type of investigation. Every fi fth household sampled for the ILFS was included in the sample for the time use module. The realised sample for the survey was over 3,000 households. All members of the household aged 5 years and older were targeted, yielding a realised sample of 10,553 respondents with valid diary information after cleaning. The data were weighted so as to be representative of the country’s population aged 5 years and older as a whole. At the time the ILFS was conducted, the country’s population aged 5 years and older was estimated at close to 30 million people.
