U.S. Bureau of Labor Statistics U.S. Bureau of Labor StatisticsMulti-year microdata files that combine several years of ATUS microdata are available for 2003-2009 and for 2003-2010. Because of changes to ATUS methods from 2003 to 2010, these multi-year files are not identical to what would be produced by simply combining single years of ATUS data. Multi-year microdata files for 2003-11 are forthcoming.
Researchers not wishing to use the multi-year files, and preferring instead to combine single-year ATUS microdata must be aware of changes to ATUS survey methods from 2003 to 2010. This page includes links to resources that will assist researchers when determining how to create multi-year ATUS data sets and provides guidance about which population weighting variables are comparable between years.
There were no changes in the method used to generate statistical weights (the variable TUFINLWGT) on the ATUS data files from 2006 to 2011. However, the method used to generate the weighting variable TUFINLWGT on the ATUS files changed each year from 2003 to 2006. Thus, researchers who create multi-year data sets should not use the weighting variable TUFINLWGT for all years.
Valid weights for various combinations of years
Combining 2003 through 2011 data files (or any combination of files from these years)
Combining 2003 through 2005 data files (or any combination of files from these years)
