The two graphs illustrate the changes in ownership of electrical appliances and the amount of time spent on housework in households in one country from 1920 to 2019.
The first graph shows the percentage of households that owned washing machines, refrigerators, and vacuum cleaners over this period. Ownership of refrigerators and vacuum cleaners followed a similar pattern, both increasing from 1920 to 1980. Refrigerators started at 3% in 1920 and reached 100% by 1980, while vacuum cleaners started at 30% and also reached 100% by 2000. In contrast, the ownership of washing machines showed a different trend. Initially the highest at 40% in 1920, it increased to 70% by 1960. However, it then declined slightly to about 65% in 1980 before rising again to approximately 75% by 2019.
The second graph depicts the number of hours spent on housework per week per household over the same period. The overall trend was a significant decrease. In 1920, households spent around 50 hours per week on housework. As more electrical appliances were adopted, this number dropped sharply to about 20 hours per week by 1980. The figure remained stable until 2000 and then continued to decrease, reaching roughly 10 hours per week by 2019.
In summary, the graphs highlight the increase in household appliance ownership and the corresponding decrease in time spent on housework from 1920 to 2019.
