On the other hand the time used for household chores significantly decreased from 1920 to 2019.
According to the first graph, while refrigerator had the lowest percentage of slightly above zero, it experienced an upward trend until 1980 when it reached its plateau of 100% and it remained unchanged until 2019. A similar change can be seen for vacuum cleaner with a dramatic surge from 30% to 90% over 60 years. Then it peaked at 100% in 2000. Among these three devices only washing machine ownership percentage fluctuated over time with a slight fall between 1960 and 1980. Considering the second chart, it is evident that each family spent 50 hours per week for tasks like laundry, cooking, and cleaning in 1980. This number, however, experienced a gradual decrease from 1920 to 1980 by around a fall of 14 hours weekly. The trend there moved steadily till 2019 with only 11 or 12 hours.
