Professor Jonathan Gershuny first developed the Multinational Time Use Study (MTUS) in the mid 1970s. While working at the University of Bath with Sally Jones, Professor Gershuny developed a single dataset with common series of background variables and total time spent per day in 41 activities. The original MTUS allowed comparison of British time use data with the 1965 Szalai Multinational Time Budget Study and data from Canada and Denmark. The MTUS since has grown to offer harmonised episode and context information and to encompass over 60 datasets from 25 countries, including recent data from the HETUS, ATUS, and other national level time use projects. Professor Gershuny and Dr Kimberly Fisher presently manage the study in collaboration with other time use scholars. This site provides access to the MTUS data and documentation, and offers advice on the use of this dataset. At present we are undertaking a wholesale upgrade of the MTUS. This includes removing some less used variables, adding new variables, new surveys, and upgrading the documentation. You will see a number of changes on this area of the CTUR website over the next few months. These changes will include the introduction of survey metadata variables alongside the time diary variables. Please bare with us while these changes are added. At this time, the new documentation has been uploaded.
