Hofferth, Sayer lead Time Use Data for Health and Well Being

R01 provides five years of funding to continue development of the IPUMS-Time Use tool

MPRC continues its commitment to time use research with the recent award of an NIH R01 valued at $2.6 million to continue development of the IPUMS-Time Use research tool. The project will be led by MPRC Research Professor Sandra Hofferth and MPRC Faculty Associate Liana Sayer, working with colleagues from the Minnesota Population Center, University of Minnesota, and the Centre for Time Use Research, University of Oxford.

The first five-year phase of the project focused on integrating data from the American Time Use Surveys (ATUS), a series of annual surveys begun in 2003. During the past four years, Phase II, IPUMS-Time Use expanded to three integrated databases: American Time User Survey Extract Builder (ATUS-X), American Heritage Time Use Study Extract Builder (AHTUS-X), and the Multinational Time Use Study Extract Builder (MTUS-X).

It now delivers harmonized time diary data from eight countries spanning Central / Western Europe and North America from the second half of the 20th century, allowing consistent analysis of variation over time and space. This most recent award seeks to expand the database, enhance the data and metadata, improve data infrastructure and access, and support the research community. There are four specific aims:

  1. to add five new years of ATUS data from 2016 to 2020 to ATUS-X; to double the number of countries included in MTUS-X, in collaboration with the Centre for Time Use Research, University of Oxford, by incorporating new countries from Latin America (Brazil, Mexico), Eastern Europe (Hungary), Western Europe (Italy, Germany), South Asia (Pakistan), East Asia (Republic of Korea), and South Africa; and to incorporate newly digitized U.S. time diary data from the 1920s and 1930s;
  2. to create and disseminate a variety of new variables including time use of other family members, metabolic equivalents of energy exerted, activity context variables, household- and person-level variables, verbatim activity descriptions for some U.S, datasets, and variables describing sample characteristics;
  3. to deliver alternative data formats, support online data analysis, develop new metadata to improve the delivery of critical sample- and variable-level information to users, and enhance search capacity; and
  4. to develop new online training capabilities and to continue to provide user support, training, and outreach.

The third phase of IPUMS-Time Use will provide high quality cross-national data on countries of great importance for our future, not only representing North America and Central / Western Europe, but also Africa, Asia, Eastern Europe, and Latin America.
