The two line charts indicate the percentage of households owning electrical gadgets and the number of hours people spend doing housework per week between 1920 and 2019.

Overall, the proportion of people using electrical devices increased significantly over the period; as a result, people spend far less time doing housework.

Looking at the first chart, almost no one had the refrigerator in 1920, but through 60 years, there was a dramatic growth in the proportion of households owning this machine, reaching a peak of 100% in 1980. Following the same trend, the figure for residents having the vacuum cleaner climbed significantly, just 30% at the beginning, but in the year 2019, everyone could possess this device. Regarding the washing machine, the percentage of households owning this appliance was the highest in 1920 (at 40%), then fluctuated over 80 years, and at the end of the period, about 60% of households had this machine.
