title: Version 1

description: The American Time Use Survey (ATUS) collects information on
 how people living in the United States spend their time. Data
 collected in this study measured the amount of time that people spent
 doing various activities in 2005, such as paid work, child care,
 religious activities, volunteering, and socializing. Respondents were
 randomly selected from households that had completed their final month
 of the Current Population Survey (CPS), and were interviewed two to
 five months after their household's last CPS interview. Respondents
 were interviewed only once and reported their activities for the
 24-hour period from 4 a.m. on the day before the interview until 4
 a.m. on the day of the interview. Respondents indicated the total
 number of minutes spent on each activity, including where they were
 and whom they were with. Except for secondary child care, data on
 activities done simultaneously with primary activities were not
 collected. Part 1, Respondent and Activity Summary File, contains
 demographic information about respondents and a summary of the total
 amount of time they spent doing each activity that day. Part 2,
 Roster File, contains information about household members and 
 nonhousehold children under the age of 18. Part 3, Activity File,
 includes additional information on activities in which respondents
 participated, including the location of each activity and the total
 time spent on secondary child care. Part 4, Who File, includes data on
 who was present during each activity. Part 5, ATUS-CPS 2005 File,
 contains data on respondents and members of their household collected
 two to five months prior to the ATUS interviews during their
 participation in the Current Population Survey (CPS). Parts 6-10
 contain supplemental data files that can be used for further analysis
 of the data. Part 6, Case History File, contains information about the
 interview process, such as identifiers and interview outcome codes.
 Part 7, Call History File, gives information about each call attempt,
 including the call date and outcome. Part 8, Trips File, provides
 information about the number, duration, and purpose of overnight trips
 away from home for two or more nights in a row. Part 9, Replicate
 Weights File I, contains base weights, replicated base weights, and 
 replicate final weights for each case that was selected to be 
 interviewed for ATUS, while Part 10, Replicate Weights File II, 
 contains replicate weights that were generated using the 2006 
 weighting method. Demographic variables include sex, age, race, 
 ethnicity, education level, income, employment status, occupation,
 citizenship status, country of origin, relationship to household
members, and the ages and number of children in the household.
description: The data contain weight variables which should be used in
analyzing the data. Unweighted data are not representative of the
population due to differences between population groups in both
sampling and nonresponse. ATUS weight variables include the ATUS final
weight (TUFINLWGT), which indicates the number of person-days the
respondent represents, the ATUS base weight (TUBWGT), and a ATUS final
weight based on 2006 weighting methodology (TU06FWGT). ATUS weights
were selected from the Current Population Survey (CPS), and CPS
weights (after the first-stage adjustment) are the basis for the ATUS
weights. These base weights were adjusted to account for the fact that
less populous states were not oversampled in ATUS, as they were in the
CPS. Further adjustments were made to account for the probability of
selecting each household within the ATUS sampling strata and the
probability of selecting each person from each sample household. Part
9 contains replicate weights for the variable TUFINLWGT, as well as
base weights, while Part 10 contains replicate weights for the
variable TU06FWGT. ATUS replicate weights were based on the replicate
weights developed for the CPS. ATUS began with the CPS replicate
weight after the first-stage ratio adjustment, and each replicate was
processed through all of the stages of the ATUS weighting procedure.
The CPS replicate weights were based on a modified balanced
half-sample method of replication, developed in the 1980s by Robert
Fay. For more information about the replicate weights, see the
publication, Technical Paper 63RV: Current Population Survey -- Design
and Methodology, available via the
Bureau of Labor
Statistics Web site. More information on the weighting variables
used in this study can be found in the User Guide.
description: Response Rates: The overall response rate was 56.6 percent.
description: This survey used a stratified, three-stage sampling
design. Respondents were randomly selected from households that had
completed their final month of the Current Population Survey (CPS).

description: computer-assisted telephone interview (CATI)(1) The data available for download are not weighted,
 and users will need to weight the data prior to analysis. (2) The
 files in Parts 6-10 have not been processed by ICPSR staff, and are
 being distributed in essentially the same form in which they were
 received. (3) The data file in Part 1 contains the linked Respondent
 and Activity Summary files. Information on how to link files, produce
 time-use estimates, and combine multiple years of data can be found in
 the User Guide and via the
 American Time Use
 Survey, 2005, Web site. (4) Variable and value labels were added in
 several variables. (5) The following variables were converted from
 character to numeric: TUCASEID, HRHHID, TEHRUSL1, TEHRUSL2, TUCC2,
 TUCC4, TEIO1ICD, TEIO1OCD, PEIO1ICD, PEIO1OCD, PEIO2ICD, and
 PEIO2OCD. (6) The CASEID variable was added to the data file in Part 1
 for use with online analysis. (7) Some variables contain implied
 decimal places, as noted in their variable labels. (8) The activity
 code variables in Part 1 are preceded by the letter "T" and include a
 6-digit activity classification code. Activity classification codes
 and examples of activities can be found in the ATUS Coding Lexicon.
 For more information about the ATUS Coding Lexicon, please refer to
 the User Guide. (9) The Trips file in Part 8 does not contain weights
 and should be used with caution. More information on the Trips file
 can be found in the documentation and via the
 American Time Use
 Survey, 2005, Web site. (10) Published tables and charts showing
 time-use estimates for major activity categories, selected detailed
 activities, and selected demographic characteristics are available via
