In 1992 the Australian Bureau of Statistics conducted its first ever national survey of time use, a new information resource which provides information about the unpaid work that takes place at home. The author analysed this data in conjunction with earlier, non-national time-use surveys conducted in 1987 and 1974 in order to study how the time that men and women allocate to unpaid work has changed. The three surveys were mathematically standardised so that all the results were given in terms of Sydney, May-June. The surveys cover time devoted to cooking, laundry, home maintenance and car care, shopping, child care as well as other related activities.
