The Bureau of Labor Statistics does surveys and collects information on how Americans spend their time. If you are a data miner, check out the 2004 report. Here are a couple of things that caught my eye.
On the days that both worked, employed men worked about an hour more than employed women--8.0 versus 7.2 hours.
Married persons spent more time doing household activities than
unmarried persons--2.1 versus 1.4 hours per day--and women, regard-
less of marital status, spent more time doing these activities than men.
--On an average day, persons age 65 and over spent the most time--7.3 hours--participating in leisure and sports activities of any age group; 35- to 44-year-olds spent the least time--4.2 hours.
In households with the youngest child under age 6, time spent providing primary childcare averaged 2.7 hours for women and 1.2 hours for men. Physical care, playing with children, and travel related to childcare accounted for most of the time spent in primary childcare activities. (See table 9.)
--For adults living with children under age 6, women provided an average
of 1.2 hours of physical care--such as bathing, dressing, or feeding a child--per day to household children, while men provided about one-third of this amount--0.4 hour (about 24 minutes). (See table 9.)
