The first line graph outlines how electrical appliance ownership in households in a country changed during a century, commencing from 1920. The second chart delineates how it the time spent on household work per week by the citizens in this country.
As a general trend, with the increasing number of electrical devices possessed by families, their need for doing housework significantly declined.
As the graph reveals, only 30 percent of households in this country had vacuum cleaners and four out of ten families had washing machines in 1920. Refrigerators were a rare electrical appliance at that time. Just after two decades, however, shot up, and almost half of the families owned these three electrical items in their homes. More families started to own such devices and at the beginning of the twenty-first century, almost all households had fridges and vacuum cleaners. The washing machine was owned by more than 70% of families which slowly but steadily increased till 2019. At that point, there was hardly any family without a refrigerator or vacuum cleaner.
with the increasing number of families owning those electrical appliances, their need for doing household work like preparing meals, cleaning and washing clothes remarkably diminished. While they used to work for 50 hours a week doing such work in 1920, it decreased to 20 hours in 1960
