The provided line charts illustrate changes in ownership of electrical appliances and time spent on household chores in households of a particular country from 1920 to 2019.
Overall, a significant increase in the adoption of electrical appliances like washing machines, refrigerators, and vacuum cleaners can be observed, while there was a notable decline in the hours dedicated to housework per week.
Notably, in 1920, no households owned a refrigerator, but by 1960, the ownership had surged to 90% and eventually reached 100% in 1980, maintaining that level until 2019. Similarly, the ownership of vacuum cleaners started at 0% in 1920, increased to 60% by 1960, and reached full saturation by 2000 after remaining stable at 80% from 1980. The ownership of washing machines saw a steep rise from 30% in 1920 to over 70% in 1960, slightly dropped to 60% in 1980, and then increased again to over 70% by 2019.
In contrast, the time spent on housework per week experienced a sharp decline from 50 hours in 1920 to 30 hours by 1960, further decreasing to 20 hours in 1980, and finally settling at 15 hours from 2000 to 2019. This indicates a substantial reduction in the time allocated for household chores over the years, reflecting the impact of technological advancements in alleviating domestic work burdens..
