the two graphs presented illustrate the changes of households with electrical appliances and the number of hours housework spent per week over the period from 1920 until 2019.
Overall, the percentage of refrigerator usage with electrical appliances sharply rose, while the duration of houseworks shows a downward trend over the period.
There are three percentage of households that shown in graph, such as washing machine, refrigerator, and lastly vacuum cleaner. At the beginning, in 1920, washing machine had the largest percentage of households, meanwhile with no percentage, refrigerator is the least, which mean no one used refrigerator at that time. By 1960, the number of refrigerator escalated rapidly to 90%, consequently replaced the amount of washing machine. During the time until 2019, the percentage of washing machine usage also gradually increased following the number of refrigerator. In the other hand, vacuum cleaner fluctuated steadily with least changes of percentage until 2019.
Initially, the work hours of housework was at the peak which is around 50%. Over time, the duration that spent by houseworks is fallen gradually to 10% at the end of 2019.
