The two line graphs illustrate the changes in ownership of electronic devices, including washing machines, refrigerators, and vacuum cleaners, and the amount of time spent on household chores in one country from 1920 to 2019.
Overall, there was a notable growth in the ownership of electronic devices, while the time devoted to household chores experienced a significant reduction over the period.
Refrigerators were owned by just 1% of households in 1920, but this figure surged to 52% by 1940 and reached 90% by 1960. Ownership continued to climb, reaching 100% in 1980 and remaining at this level through to 2019. Similarly, vacuum cleaners were initially owned by 30% of households in 1920. Their ownership grew steadily to 50% in 1940, 70% in 1960, and 90% in 1980. They then saw a dramatic rise to 100% by 2000 and maintained this rate until 2019.
In contrast, the adoption of washing machines showed a more gradual progression. Starting at 40% in 1920, ownership advanced to 60% by 1940 and 70% by 1960. However, there was a slight dip to 65% in 1980, followed by a further rise to 70% in 2000 and 72% in 2019.
The time spent on household chores diminished considerably over the period. Households began by spending 50 hours per week on chores in 1920, but this figure dropped to 35 hours by 1940, 20 hours by 1960, and further decreased to just 10 hours by 2019.
