The given line graphs illustrate the proportion of households who were involved in the changes in ownership of electrical devices and the number of hours spent per week on household activities in a country from 1920 to 2019.
Overall, it can be seen that the percentage of households that transferred appliances witnessed an increasing trend over the course of 100 years, while the working hours per week decreased.
In detail, 40% of people transferred their ownership for washing machines in 1920, while 30% of households were responsible for vacuum cleaner changing, and a mere 2% of people changed their refrigerator. After sixty years, this trend showed a significant rise for refrigerators at 100% and vacuum cleaners at 90% by 1980. The figure for the washing machine demonstrated a minimum change to about 65% by this time compared to the other two appliances. Finally, by the last four decades, all figures depicted rise except refrigerator. The proportion was nearly 75% and 100% for washing machines and vacuum cleaners, respectively, by 2019, while the rate for refrigerators remained the same at 100%.
By contrast, working hours per week showed the reluctancy of households. It stood at 50% in 1920 and fell to approximately 10% by 2019 after a gradual declination.
