The line graph gives information about how many people owned electrical appliances—washing machines, refrigerators, and vacuum cleaners—and the time spent doing housework in households in a specific nation from 1920 to 2019. Units of the first graph are measured in percentages of households, and units of the second graph are measured in numbers of hours a week.
Overall, it can be seen that the ownership of the three electrical appliances rose gradually, while refrigerators increased significantly compared to others. However, the number of hours a household worked gradually decreased at the end.
To begin, the percentage of households with washing machines was precisely 40% in 1920, which rose significantly to overtake the vacuum cleaner in 1960 by constituting around 70%. However, there was a slight drop in the rate in two decades to just above 60%, followed by a rapid incline to around 70% at the end of the period.
The percentage of households with refrigerators increased gradually in 16 years to 10% and continued to rise steadily throughout the period, whereas the ownership of the vacuum cleaner started at 13% in 1920, followed by a significant increase to reach 100% in 80 years, where it remained until 2019.
On the other hand, the amount of time spent doing housework gradually dropped from 15 hours to 50 hours per week over 60 years. However, there was a slight decrease in the time to reach 10 hours a week in 2019.
