The presented line graphs show information regarding the changes on electronic devices used by households, as well as the total amount of hours spent on chores that keep homes to run smoothly in a given country over a nine-decade period from 1920 to 2019. Units of measurement are calibrated in percentage of households and number of hours per week.
Overall, it can generally be reported that the percentage rate in using electronic gadgets such as washing machine, refrigerator and vacuum cleaner went up significantly, despite some fluctuations in line of washing machine, whereas, looking at time span per week in doing household, it can be seen that the line pattern was largely reversed.
From a detailed analysis, the number of refrigerator users was in substantial gain from 0 percentage in 1920 to a peak of roughly full percentage by 2000, plateauing through 2019, meanwhile, surpassing the left two lines through 1960. Then, those using vacuum cleaner and washing machine rose remarkably in 1920, passing midway of 70 percentage in 1960, and people relying on vacuum cleaner were nearly three times as much as that making use of washing machine by the end of the period.
Regarding hours per week, this appears to reverse the use of electronic machines, with an early high of 50 hours in 1920, falling consistently to 10 hours in 2019. This meant that timeframe spent on household chores in 1920 was four times as low as that in 2019.
