The provided charts demonstrate the percentage of electrical appliances’ ownerships, namely washing machines, refrigerators, and vacuum cleaners in various households and the amount of hours of housework done in one household per week.
Overall, it is evident in the first chart that the ownerships of electrical appliances dramatically increased throughout the period of 1920 to 2019. As a result, the number of hours spent on housework, as seen in the second chart, reduced drastically over time.
According to the first line graph, 40% of households owned washing machines in 1920. With a slight drop to 65% in 1980, this percentage moderately rose to around 75% by 2019. Despite having the most ownerships in 1920, washing machines became the least common appliance in households in 2019, compared to refrigerators and vacuum cleaners. In contrast, although the percentage of households having refrigerators started at 0% in 1920, this figure climbed significantly to 100% in 1980, where it would remain until 2019. Similarly, vacuum cleaner ownerships began with a percentage of 30% in 1920, rose consistently to 100% in 2000, then stabilizing at the same level as refrigerator ownerships by 2019.
Regarding the second line graph, it is clear that the widespread use of electrical appliances in this period has significantly reduced the amount of time spent on housework. From 1920 to 1960, the hours that households dedicated to housework dropped from an average of 50 hours to 20 hours, then gradually decreased to only 10 hours per week by 2019.
