This study utilizes the International Classification of Activities for Time-Use Statistics (ICATUS) to delineate non-productive and productive activities. The study uses data from the Tanzania country-wide survey on time-use conducted between January and February 2005. An attempt was made to examine some factors associated with time-use on non-productive activities. The factors included age, residence, marital status, education and gender. The findings showed statistically significant association between non-productive activities and each of the above factors. The effect of these factors on involvement in non-productive activities was tested through a logistic regression. The results revealed that residence and gender have significant effect on non-productive activities while education has an insignificant effect (p=0.07). In particular the findings showed that respondents in rural areas are 1.5 times less likely to be involved in nonproductive activities than those in urban areas. With regard to gender the results suggested that women are 2.4 times more likely to be involved in non-productive activities than men.
