The image contains two line graphs, the first titled "Percentage of households with electrical appliances (1920-2019)" and the second titled "Number of hours of housework per week, per household (1920-2019)"; both x-axes range from 1920 to 2019 in increments of 20 years, and y-axes vary in scale and units. The first graph depicts 4 lines representing washing machines, refrigerators, vacuum cleaners and electric irons, with data points at 1920:0%, 1940:washing machines 20%, refrigerators 10%, 1960:washing machines 40%, refrigerators 50%, vacuum cleaners and electric irons 10%, 1980:washing machines 60%, refrigerators 90%, vacuum cleaners 20%, electric irons 30%, 2000:washing machines 80%, refrigerators 100%, vacuum cleaners 60%, electric irons 40%, 2019:washing machines 100%, refrigerators 100%, vacuum cleaners 80%, electric irons 70%. The second graph shows a single line for "Hours per week" declining from 1920:50, 1940:40, 1960:30, 1980:20, 2000:10, 2019:<5.

The charts provided depict the changes in ownership of electrical appliances and the amount of time spent doing housework in households in a particular country between 1920 and 2019.
Overall, there has been a significant increase in the ownership of electrical appliances such as washing machines, refrigerators, vacuum cleaners, and electric irons over the past century. Additionally, the amount of time spent on housework per week has shown a steady decline from 1920 to 2019.
The ownership of electrical appliances has seen a remarkable increase over the years. In 1920, no households had washing machines, refrigerators, vacuum cleaners, or electric irons. However, by 2019, all households had washing machines and refrigerators, with ownership percentages reaching 100%. Vacuum cleaners and electric irons also experienced substantial growth, with ownership rates of 80% and 70% respectively in the same year.
Conversely, the number of hours spent on housework per week has shown a consistent decrease over the decades. In 1920, households spent an average of 50 hours per week on housework, which steadily declined to less than 5 hours by 2019. This downward trend indicates a shift towards more efficient household chores facilitated by the widespread adoption of electrical appliances.
