The two line charts below present both the evolution in ownership of three electrical appliances and the number of hours of housework per week in one country from 1920 to 2019.
Overall, it can be seen that the proportion of vacuum cleaner and refridgerator observed some significant increase throughout the period, while washing machine stats changed much less. During the same time, the amount of time spent doing housework slowly decreased.
In detail, the exact numbers of the two electrical devices that had advancing status were from 0 to 100 percent for refrigerator and from 30 to 100 percent for vacuum cleaner. Noticeably, both percentages reached a peak number before 2010 (1980 for refrigerator and 2000 for vacuum cleaner) and remained unchanged until 2019. In contrast, the rate of washing machine never reached its highest. Its poportion gradually increased to 70 in 1960, and for the rest of the years it remains stable from 60 to approximately 70 until 2019.
Moving on the quantity of housework time per week, the hours spent on doing chores were seen to decrease rapidly from 1920 to 1960. After that, the number remains consistent and lessen slightly between 2000 and 2019.
