The line graphs illustrate the alterations in the ownership of electrical appliances such as washing machines, refrigerators, and vacuum cleaners, and the average time spent doing housework in a specific nation from 1920 to 2019.
Overall, it is noticeable that, despite slight fluctuations in the percentage of households owning washing machines, all three appliances’ ownership increased during the given period. However, the amount of housework per week decreased.
Washing machines were the most common appliance in 1920, with ownership at nearly 40%, but this increased gradually during the following 4 decades to reach approximately 70%. Despite a slight decrease in washing machine ownership in 1980, this number rose steadily for the rest of the period to around 75% in 2019. The owners of refrigerators were the lowest in 1920, with just over 0%, and it saw a dramatic boom in the next 60 years to reach 100% and stayed at this level until the end of the period.
Vacuum cleaners’ ownership was 30% at the beginning of the recorded time. However, it witnessed a considerable rise by 2019 to 100% ownership. In contrast, the number of hours of housework decreased from 1920 to 1960 by around 50% and 29%, respectively. The number of hours declined moderately for the next 59 years to reach its lowest rate in 2019, just over 10%.
