arative time use data resources: the Multinational Time Use Study and the American Heritage Time Use d Kimberly Fisher, Jonathan Gershuny, Anne H. Gauthier, and Muriel Egerton AHTUS PURPOSE: Allow analysis of cross-time changes in national accounts in the USA DATA INCLUDED (release 1) • 1965-1966 University of Michigan studies – both Jackson, Michigan (Szalai) and 44 metropolitan areas samples • 1975-1976 ICPSR 4 wave longitudinal study • 1985 ICPSR mail back sample • 1992-1994 NHAPS • 2003 ATUS Future data to be added 1995 NHAPS extension, 1998-2001 ICPSR, 2004 ATUS Data Structure - main files Supplementary Files Covers diarists aged 18+ Main respondent only 1975/76 1975/76 spouse + main respondent 3 data files per survey - Background/demographic - Episode (main, secondary, in/outside, location, who else present, start/stop time, duration) - Aggregated time (sole activity & act with secondary childcare summed separately) Child (aged 0-17) diaries 1992/94 Child (aged 15-17) diaries 2003 Early analysis Figure 4.4b: Women - Total Housework by surve y and child coresidence (aged 19-64) no kids Figure 4.4a: Me n - Total Housework by surve y and child coresidence (aged 19-64) no kids kids aged under 5 80 kids aged under 5 100 The recently released American Historical Time Use Study (AHTUS) was developed for the Glaser Progress Foundation at Yale University. From 2003, the Bureau of Labor Statistics in the USA began collecting first continuous time use data as an add-on to the CPS. Not only is this American Time Use Study (ATUS) the first continuous record of changes in daily activities, this dataset also covers the largest time use sample yet collected. The ATUS will allow the monitoring of trends in the use of time in the USA, but as a new study, it does not independently allow a backward view of change over time. The AHTUS has harmonised older USA time use studies into a format for cross-time analysis with the ATUS. Both projects have entailed methodological work to improve the quality of the time use data and to optimise the harmonisation of the variables for cross-time and crossnational analysis. Both datasets are free for use to the research community. The AHTUS will inform the next generation of the MTUS, which will include harmonised sequence, who else is present, and location data in addition to aggregated activity summaries. kids aged 5 to 17 kids aged 5 to 17 80 minutes 60 minutes This poster details developments of two harmonised datasets created at the Institute for Social and Economic Research (ISER) at the University of Essex (UK) in conjunction with the Department of Sociology at the University of Calgary (Canada). The older dataset, the Multinational Time Use Study (MTUS), sprang from the inspiration of Professor Jonathan Gershuny, then working with Sally Jones at the University of Bath in the early 1980s. The early MTUS built from the 1965 Szalai Multinational Time Budget Study and harmonised mainly European datasets collected in the early 1960s through the mid 1980s into a common series of background variables and total time spent per day in 41 activities. The MTUS has grown to encompass over 50 datasets from 19 countries, and is now incorporating recent data from the HETUS, ATUS, and other national level time use projects. 40 60 20 40 0 20 1960s Jackson 1960s National 1970s 1980s 1990s ATUS 2003 1960s Jackson 1960s National 1970s 1980s 1990s ATUS 2003 http://www.iser.essex.ac.uk/mtus/ MTUS PURPOSE: Allow analysis of cross-time and cross-national changes in daily activities DATA INCLUDED (release 5.5.2) Australia 1987, 1992, 1997 Austria 1992 Canada 1971/72, 1981, 1986, 1992, 1998 Denmark 1964 Finland 1979, 1987/88, 1999/2000 France 1998/99 Germany 1992 Italy 1989 Netherlands 1975, 1980, 1985, 1990, 1995, 2000 Norway 1971, 1981, 1990/91, 2000/01 Slovenia 2000/01 South Africa 2000 Sweden 1990/91, 2000 UK 1961, 1974/75, 1983, 1987, 1995, 2000/01 USA 1965/66, 1975/76, 1985, 1992/94, 1998/01, 2003 Current MTUS activity codes Total Minutes in 24 Hours AV1 AV3 AV5 AV7 AV9 AV11 AV13 AV15 AV17 AV19 AV21 AV23 AV25 AV27 AV29 AV31 AV33 AV35 AV37 AV39 AV41 paid work AV2 second job AV4 travel to/from work AV6 doing housework AV8 gardening AV10 childcare AV12 for dressing/toilet AV14 eat meals or snacks AV16 travel for leisure AV18 engage in sports AV20 walking AV22 civic, volunteer AV24 dances/parties AV26 pubs AV28 visiting friends AV30 TV/video AV32 study AV34 read paper/magazine AV36 conversation AV38 knit, sew AV40 missing paid work at home school, classes cook, wash up doing odd jobs shopping domestic travel receive services sleep on excursions watch sports religious activity cinema/theatre social clubs restaurants radio listen to recording read books relaxing entertain friends other hobbies Future work •Update activity list • Add recent datasets • More time series • Harmonised sequence data • Separately aggregated sole & simultaneous activity • Add context variables • End 2006 for new prototype
