Time-use surveys measure the amount of time people spend doing various activities, such as work, childcare, housework, watching television, volunteering, and socializing.
Data collection began in January 2003, and the first estimates were published on September 14, 2004.
ATUS is sponsored by the Bureau of Labor Statistics and conducted by the U.S. Census Bureau. The Census Bureau collects and processes the data.
Households that have completed their final (8th) month of the Current Population Survey are eligible for the ATUS. From this eligible group, households are selected that represent a range of demographic characteristics. Then, one person age 15 or over is randomly chosen from the household to answer questions about his or her time use. This person is interviewed for the ATUS 2-5 months after his or her household's final CPS interview.
The ATUS Respondent's Web site provides additional information for those selected to participate in the ATUS.
Researchers, journalists, educators, sociologists, economists, government lawmakers, lawyers, and individuals are all users of time-use information. The survey produces nationally-representative estimates of the U.S. population's time use by labor force status, demographic characteristics, and other factors. Analysts are able to compare Americans' time use with similar data from many other countries that have time-use surveys. To find out more about how time-use data can be used, go to the ATUS Overview.
BLS publishes a news release of time-use estimates annually. BLS periodically publishes news releases with time-use estimates for certain populations or topics, such as married parents and unpaid eldercare. All of the news releases are available on the ATUS News Releases Web page. In addition, ATUS microdata files are published annually which are available for free at www.bls.gov/tus/data.htm.
Yes, public use microdata files and documentation are available for free from the ATUS website. Links to the microdata are available on the ATUS home page under the heading Data Files. Information about working with the ATUS data files is available on the ATUS How To page.
Many variables appear on the ATUS public use microdata files. The ATUS data dictionaries provide information about the variables that appear on the microdata files and explain how the files can be linked. For a list of variables that are frequently used to tabulate the ATUS microdata, see the ATUS documentation Frequently Used Variables (PDF).
ATUS data are collected via telephone interviews. Census Bureau interviewers use Computer Assisted Telephone Interviewing, a system that automatically advances interviewers to the next question based on a respondent's answers to previous questions. Respondents receive an advance letter and pamphlet explaining the purpose of the ATUS and notifying them of the day they will be called. The main part of the ATUS interview is the 24-hour time diary. This part of the interview is used to collect a detailed account of the respondents activities, starting at 4 a.m. the previous day and ending at 4 a.m. on the interview day. For each activity reported, the interviewer asks how long the activity lasted. For most activities, the interviewer also asks who was in the room or accompanied the respondent during the activity and where the activity took place.
Respondents are interviewed one time about how they spent their time on one day.
Households without telephones and those that did not provide a telephone number in the CPS can be selected for the ATUS sample. In a letter about the survey, Census asks selected individuals in these households to call a toll-free number to complete the interview.
After the interview is complete, coders assign a 6-digit code from the ATUS activity classification system to each activity. The classification system contains 17 major time-use categories, each containing two additional levels of detail. These 17 coding categories are recombined into more relevant analytical categories for publication. To find out more about the ATUS coding categories, see the ATUS Coding Lexicons.
The ATUS periodically adds special, topical questions. These questions are added to the end of the ATUS interview, in a 5-minute interval of survey time referred to as a module. Before a module is implemented, several requirements must be met: the survey matter must fall within the public interest, there must be a relevance to time use, and the questions must be tested for comprehension.
Time-use estimates for various activities and selected demographic and labor force characteristics are available on the ATUS Web site under the headings News Releases, ATUS Database, Charts and Tables. In addition, a limited number of unpublished tables are available from the ATUS staff. These tables include time-use estimates by age, race, ethnicity, employment status, educational attainment, marital status, the presence and age of household children, and other detail. For more information about these unpublished tables, contact ATUS staff.
The ATUS Database of time-series data is available from LABSTAT, the Bureau of Labor Statistics public database. The ATUS time series correspond to the annual and quarterly estimates presented in the annual news release and estimates appearing on tables A-1 and A-2. Guidance for extracting time-series data is available on the ATUS LABSTAT tips page.
ATUS staff members are unable to produce tabulations upon special request.
Unpublished tables showing time-use estimates for states, Census regions (Midwest, Northeast, South, and West), and Census divisions (Mountain, New England, Pacific, etc.) are available by contacting ATUS staff. This map shows the Census regions and divisions. Estimates on these tables are 5-year averages.
Variables identifying the state in which survey respondents resided at the time of the interview, their Census region, Census division (beginning in 2014), and metropolitan status appear on the ATUS-CPS data file. Please see the ATUS-CPS data dictionary for more information about the variables that appear on the ATUS-CPS file.
The only simultaneous activity ATUS collects is secondary childcare. Secondary childcare is care for children under age 13 that is done while doing something else as a primary activity. This includes times when respondents were loosely supervising a child while doing something else, such as keeping an eye on a child while cooking dinner; it also includes times when respondents were more actively engaged with a child while doing something else, such as when respondents were reading to a child while traveling or changing a childs diaper while talking on the phone. The ATUS does not collect information about any other simultaneous activities. If a respondent reports doing more than one activity at a given time, the interviewer first asks her if she can separate the activities into different time intervals. If she is unable to do this, the interviewer asks her which activity was her main activity and records the response. For example, if a respondent reports listening to music while reading the news for pleasure, the interviewer will ask her if she can separate the two activities into two different time intervals. If she cannot separate these activities, the interviewer will only collect the activity she reports as the main activity. Travel activities are an exception to this rule; if a respondent reports traveling along with another activity (e.g., I was listening to the radio while driving to work), the interviewer always records traveling.
From 2006-08 and 2014-15, questions about secondary eating and drinking were added to the ATUS as part of a special Eating & Health Module sponsored by the Economic Research Service of the United States Department of Agriculture. More information on this module is available on the Eating and Health Module page.
Questions about general health were included in the 2006-08 Eating and Health Module; the 2011 Leave Module (only for employed wage and salary workers); the 2010, 2012, and 2013 Well-being Modules; and the 2014-15 Eating and Health Module. More information about the modules, including the questionnaires, is available on each modules data files page: http://www.bls.gov/tus/data.htm. The 2014 Eating and Health Module data files will become available in 2016 and the 2015 Eating and Health Module data files will become available in 2017.
The ATUS does not have good data on computer use because of the way the ATUS collects activity information. Interviewers are trained to ask for more information when someone says he was "on the computer" or "using a computer." The interviewer's goal (and that of the ATUS) is to find out how the computer was being usedwhat activity was the respondent doing on the computer (playing games, doing homework, corresponding with friends, grocery shopping, banking, researching something for personal interest, etc.)? An activity code is then assigned based on how the computer was used. For example, if someone used a computer to pay bills, this would be captured in the activity category Household Activities/Household Management/Financial Management (020901). The category "computer use for leisure (excluding games)" includes computer use, but it is not comprehensive.
The American Time Use Survey (ATUS) is not a good source of information about how people use the Internet. Activities are coded based on how survey respondents were using the Internet, not whether they were using this tool. For example, if a respondent reports "ordering groceries online," this activity would be assigned the activity code for grocery shopping. If a respondent reports updating my blog, the activity would be coded as writing for personal interest. The category "computer use for leisure (excluding games)" includes some Internet use, but it is not comprehensive and it also includes non-Internet-based activities.
The American Time Use Survey (ATUS) provides measures about work at home that are derived from data collected in the diary section of the ATUS interview. In the diary, individuals report what they were doing over a 24-hour period and where they were for most activities. ATUS estimates about work at home are calculated from the times individuals reported working while at home. Work done at home includes a mix of work performed on days people were scheduled to work and on days people were not scheduled to work. Reported work times may have been as short as one minute spent checking a work email account to more than a 12-hour work shift.
The ATUS does not include any questions specifically about work schedules or formal arrangements to work from home, and so it is impossible to know whether a survey respondent who reported working from home was doing so on a scheduled work day, whether it was work done in addition to the respondent's usual work hours, or whether the respondent regularly or usually works from home.
The ATUS does not collect information on formal work arrangements or work schedules, so it is impossible to know whether someone usually works a particular shift. The ATUS does collect information about the timing of work in the diary portion of the interview, where survey respondents report how they spent their time during a 24-hour period. These data can be used to calculate the percentage of employed individuals working at a particular time of day or to identify when people employed in a particular occupation typically work.
Estimates for a particular population (e.g., men or women) show the average time individuals in the population spent doing an activity, whether or not they engaged in the activity on a given day. Estimates for participants show the average time per day people who did the activity spent doing it. For example, consider the time people spend doing laundry. The population measure for time spent doing laundry on an average day is an average for all people in the population and all days in the week, whether or not an individual spent time doing laundry on a given day, whereas the participant measure provides the average duration people who did laundry on a given day spent doing this activity. The population measure is much lower than the participant measure, because some people never do laundry and those who do typically do not do laundry every day.
The terms employed, unemployed, and not employed are used to classify people in different employment situations.
Employed persons consist of:
Persons are classified as unemployed if they do not have a job, have actively looked for work in the prior 4 weeks, and are currently available for work. Workers expecting to be recalled from layoff are counted as unemployed, whether or not they have engaged in a specific jobseeking activity.
Persons who are not employed do not meet the conditions for employment. People who are not employed include the unemployed, as well as individuals who do not have a job and are not seeking one. Many individuals who are not employed are retirees, students, or individuals caring for children or other family members.
The ATUS uses a 24-hour time diary to collect all activities, including sleeping. Interviewers have additional instructions on how to question respondents about sleep. If a respondent reports going/went to bed, then the interviewer must ask him what time he fell asleep. If it took 30 minutes or less for the respondent to fall asleep, then the interviewer categorizes the entire duration of time as sleeping. If it took more than 30 minutes for the respondent to fall asleep, then the interviewer asks the respondent if he did anything else before falling asleep, such as grooming or reading a book. If the respondent says yes, then the other activity would be recorded; if the respondent says no, the time would be collected as time spent sleeping.
The ATUS estimate for sleep time includes all sleeping activities done over 24 hours. This includes sleeping and sleeplessness. Sleeping includes activities such as sleeping, falling asleep, dozing off, napping, getting up, waking up, dreaming, cat napping, getting some shut-eye, and dozing; sleeplessness includes insomnia, tossing and turning, lying awake, and counting sheep.
Eldercare is providing unpaid care or assistance to an individual who needed help because of a condition related to aging. This care can be provided in the recipient's home, the provider's home, or a care facility, such as in a nursing home. Eldercare can involve a range of care activities, such as assisting with grooming and feeding, preparing meals, arranging medical care, and providing transportation. Eldercare can also involve providing companionship or being available to assist when help is needed, and thus can be associated with nearly any activity. Eldercare estimates are derived by summing the durations of activities during which respondents provided care or assistance for an adult who needed help because of a condition related to aging.
A condition related to aging is an ongoing ailment or physical or emotional limitation that typically affects older people, such as becoming more frail; having difficulty seeing, hearing, or physically moving; becoming more forgetful; tiring more quickly; or specific medical ailments that are more common among older adults. It also refers to existing conditions that become progressively worse as one ages.
An eldercare provider is someone who provided eldercare more than one time in the 3 to 4 months prior to the interview day. This time frame varies slightly by respondent because the question asks about care provided between the first day of a given reference month and the interview day.
Prior to 2011, the ATUS did not collect data on time spent providing eldercare. Recognizing the need for quality eldercare data, BLS had made many efforts over the years to develop questions to collect this information. In 2005, BLS hosted a subject matter expert panel to refine the concept of eldercare, to determine the most appropriate method for collecting the data within the ATUS design, and to obtain feedback on the kinds of measures that would best inform the eldercare research and policy communities. The development process over the years also included a review of existing eldercare measures, focus groups with caregivers, reviews of draft questionnaires by subject matter experts and survey methods experts, internal testing and refinement of the questions, and cognitive testing of the questions.
Questions on eldercare were introduced to the ATUS in January 2011. The ATUS eldercare questions were designed specifically to identify eldercare providers and to measure the time they spent providing eldercare. Additional information, such as the relationship between the care provider and care recipient, the age of the care recipient, and the types of care activities that care providers do also are collected. The eldercare questions replaced the questions on trips away from home.
Time-use data have been collected in over one hundred countries, including Germany, the United Kingdom, Australia, Canada, New Zealand, and South Africa. The ATUS coding system was designed to ensure that time-use information in the United States could be compared, at broad levels, with information from other countries. To learn more about surveys in other countries, go to Related Links.
The Universities of Michigan and Maryland have conducted time-use surveys periodically since 1965. The ATUS is the first federally-administered, continuous survey on time use in the United States.
Several organizations conducted time-use surveys in the United States before the ATUS began in 2003. Because of differences in methodology between these studies and ATUS, estimates produced using these studies are not directly comparable to ATUS estimates. Early efforts in the United States included USDA-sponsored studies during the 1920s and early 1930s; these studies collected time diaries from farm housewives. The University of Michigan conducted time-use studies in 1965, 1975-76, 1981, and 1985. The 1965 study's sample was intentionally drawn from a population of urban, mostly employed individuals. The University of Maryland conducted time-use studies in 1992-94, 1998, and 2001. ATUS staff can provide a list of documents containing historical time-use estimates upon request.
The University of Maryland maintains a listing of time-use surveys previously done in the United States.
Additionally, the Multinational Time Use Study (MTUS) maintained by the Centre for Time Use Research (CTUR) at the University of Oxford in the UK, maintains a harmonized file containing data from the 1965-66, 1975-76, 1985, 1992-95, and 1998-2001 time-use studies done in the U.S. This file includes ATUS microdata that have been adjusted to allow comparisons between the earlier surveys from the United States as well as from other countries. Researchers can apply to the Centre for Time Use Research to access the MTUS data files. Access is free of charge.
