However, beginning at 40%, there was a slight increase of 70% in the number of automatic washers in 1960, after that, it declined steadily until 1980, when it recovered and maintained the same level at 70% for nearly 39 years. Turning to the second graph, the amount of time spent on housework’s ratio reduced with time as it started from 50 hours each week in1920. Then, it fell continually and reached 15 hours per week in 1980. After that, it experienced a minimal drop to just only 10 hours a week in 2019.
