The line chart shows changes in the ownership of electrical appliances and the amount of time spent on housework in a country between 1920 and 2019.
Overall, the use of electrical appliances increased during the period, although refrigerator ownership did not rise steadily. At the same time, the number of hours spent doing housework per household decreased significantly.
In terms of appliances, washing machines were owned by only about 3% of households in 1920. This figure rose quickly to around 55% in 1940 and continued to increase, reaching 100% in 1980, where it stayed for the rest of the period. Similarly, vacuum cleaner ownership started at 30% in 1920 and increased gradually to about 90% in 1980. It then reached 100% in 2000 and remained unchanged afterwards. Refrigerator ownership showed a different pattern. It began at roughly 40% in 1920 and increased to around 70% in 1960. However, it fell slightly to about 65% in 1980 before rising again to nearly 75% by 2019.
On the other hand, households spent approximately 50 hours per week on housework in 1920. This number dropped to about 20 hours in 1960 and then continued to decrease slowly, reaching around 15 hours in 2000. By the end of the period, the figure fell further to just over 10 hours per week.
