The charts illustrate the changes in the use of electrical appliances and the amount of time spent on housework in households in a country between 1920 and 2019.
The first chart shows the percentage of households with electrical appliances. In 1920, about 40% of households had washing machines. This figure increased to around 70% by 1960 but then slightly decreased to about 65% in 1980, before rising again to approximately 75% by 2019. Refrigerators were not used at all in 1920, but their adoption rose steadily, reaching 100% by 1980 and remaining at that level through 2019. The use of vacuum cleaners started at 30% in 1920, increased by roughly 20% every two decades, and reached 100% by 2000, maintaining that level thereafter.
The second chart details the average number of hours spent on housework per week. In 1920, households spent 50 hours per week on housework. This number decreased significantly over the years, dropping to 20 hours per week by 1980 and further declining to about 10 hours per week by 2019.
Overall, the charts show that the percentage of households with electrical appliances, such as washing machines, refrigerators, and vacuum cleaners, increased significantly from 1920 to 2019. Conversely, the number of hours spent on housework per week per household decreased substantially during the same period.
