American Time Use Survey

American Time Use Survey — Multi-Year Microdata Files

The ATUS multi-year microdata files combine several years of previously-released and publicly-available ATUS microdata. Because changes in time use occur relatively slowly over time, it is possible to combine multiple years of ATUS data; doing so facilitates more detailed analyses about how Americans spend their time.

About ATUS Data

About the Multi-Year ATUS Microdata Files

This page includes links to the 2003-10 multi-year ATUS microdata files and supporting documentation. These multi-year files combine microdata from the 2003 to 2010 ATUS. Researchers can use these multi-year ATUS microdata files to produce their own time-use estimates or do other analyses. Each ZIP file contains a data file along with computer programs that will read the data file into SAS, SPSS, and Stata. The data files are in CSV-format (comma-separated values).

These files do not contain time-use estimates. Tables showing time-use estimates for major activity categories, selected detailed activities, and selected demographic and labor force characteristics are available on the ATUS Web site under the headings News Releases, Charts and Tables.

Differences Between the Multi-Year and Single-Year ATUS Microdata Files

While the multi-year files are similar in structure to the single-year files, there are several important differences, some, but not all, of which are mentioned here:

  1. Multi-year files are only available for the ATUS-CPS, ATUS Respondent, Roster, Who, Activity and Activity Summary files. They are not available for the Call History, Case History, Trips and Replicate Weights files.
  2. The multi-year ATUS-CPS, Respondent, and Activity Summary files contain the ATUS statistical weighting variable TUFNWGTP generated using the 2006 ATUS statistical weighting method. Researchers wishing to generate standard errors for multi-year estimates should take care to use the single-year replicate weights generated using the 2006 ATUS weighting method. For more details see the ATUS User's Guide (PDF).
  3. The 2003-10 multi-year ATUS-CPS file contains two variables that are allocation flags, but the single-year files contain many more. Please see the 2003-10 ATUS-CPS Data Dictionary (PDF) for details.
  4. The 2003-10 multi-year Respondent file contains two variables that are allocation flags, but the single-year files contain many more. Please see the ATUS 2003-10 Interview Data Dictionary (PDF) for more details.
  5. The 2003-10 Roster and Who multi-year files do not contain any allocation flags. Please see the ATUS 2003-10 Interview Data Dictionary (PDF) for more details.
  6. Because Activity codes changed somewhat between 2003 and 2010, the Activity and Activity Summary files use activity codes that appear in the 2003-10 ATUS Coding Lexicon (PDF).

There are other differences between the multi-year and single-year ATUS files. For more detailed information on these differences, please see the 2003-10 ATUS-CPS Data Dictionary (PDF) and the ATUS 2003-10 Interview Data Dictionary (PDF).
