The illustrated charts provide data concerning the ownership of electrical appliances and the amount of hours spent doing house chores between 1920 and 2019.
Overall, there is a clear correlation between the two charts. With the introduction of electrical appliances in 1920, the number of hours of housework per household dropped significantly during the years following it.
Initially, in 1920 the average household was recording a 50 hours of housework. Although washing machines’ ownership was 40% and 30% for vacuum cleaners, 50 hours of house as a significant number. After 20 years, their ownerships skyrocketed with an average of 55% of households possessing a refrigerator, a vacuum cleaner and a washing machine. Which led to lowering the hours spent on chores to 35 only.
With the improved technology, the ownership percentages of such electrical appliances surged and the amount of hours expended per week dropped to a mere 20 in 1960, 15 in 1980 and 2000, to a barely 10 in 2019. That was a result of the peak recorder in their ownerships. As per 1960, a refrigerator was in every single household and a vacuum cleaner in 90% of them. Both peaking at 100% by 2000 and 2019, with the washing machine hovering around a 70-75% during those same years.
