The presented line graphs show information regarding the changes in electronic devices used by households, as well as the total amount of hours spent on chores that keep homes running 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 machines, refrigerators, and vacuum cleaners went up significantly, despite some fluctuations in the line of washing machine, whereas, looking at time span per week in doing housework, 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 in 1920 to a peak of roughly full percentage by 2000.It then plateaued through 2019, however it still surpassed the left two lines through 1960. Then, those using vacuum cleaner and washing machine rose remarkably in 1920, starting from 30 percent in the former and 40 percent in the latter, increasing constantly to 100 percent and over 70 percent respectively. Therefore, it can be said that people relying on vacuum cleaner were nearly three times as much as those making use of washing machine by the end of the period.
Regarding hours each 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 the time spent on domestic duties in 1920 was four times as low as that in 2019.
