The charts below illustrate the percentage of households with electrical appliances and how much time per weeks people spending to do this from 1920 to 2019. Overall, the time using electrical devices increased dramatically whereas the time doing households decreased rapidly. Significantly, the figure for Fridge and Vacuum cleaner were almost the highest one through the period. Looking closely at the first line graph, it is obvious that the figure for using machines to do housework all was an upward trend. The data of using Vacuum cleaner and refrigerator increased quickly. For instance, the figure for using Vacuum cleaners in 2019 was approximate 70% more than in 1920. Additionally, the data for using fridges in 2019 was about three times as in 1920. However, the percentage of washing machines less significant increased than others with merely about 40 % in 1920 and up to nearly 72% in 2019. Changing to the second line graph which was about the time people spent on housework. It was clear that they spent fewer hours of a week doing household because of electrical machines. For example, in 1920, it took them 50 hours to do the laundry or prepare for the meal while in 2019, they only spent 10 hours a week doing that.
