About AHTUS

The American Heritage Time Use Study, a database of national time-diary samples collected over six decades, includes harmonised background, activity, location, mode of transport and who else was present variables. The AHTUS is suitable for a wide range of investigative purposes.

These data are freely available to the research community.

The data are harmonised by the Centre for Time Use Research( CTUR) at the University College London. The initial development of the AHTUS allowing release 1 in May 2006 was conducted under an agreement with Yale University (Program on Non-Market Accounts), and was sponsored by the Glaser Progress Foundation. Some amendments to this dataset made from December 2005 through December 2011 were funded by the Economic and Social Research Council. From January 2012 through 2017, further additions and upgrades to the AHTUS have been (and will be) funded by a combination of grants provided by the Economic and Social Research Council and the US National Institutes of Health.
