The line graphs illustrate the number of households ownering electrical appliances in percent and the weekly hours allocated to doing housework in each house in a specific country. The time frame is a century period from 1920 to 2019.
Overall, it is apparent that while the percentage of households utilizing electric devices has increased, the number of hours each week that is spent on housework has been on the decline.
In 1920, roughly no citizens used refrigerators, whereas 30 percent and 40 percent of households took advantage of vacuum cleaners and washing machines, respectively. Using refrigerators witnessed an upsurge of 90 percent following the 40 years, but there was a more steady rise in utilizing the other two appliances during the same period, reaching 70 percent. After that, although the washing machine usage stayed more or less the same until 2019, the use of refrigerators and vacuum cleaners elevated to 100 percent of the public.
Time spent on housework stood at 50 hours a week in 1920. A sharp decrease of 30 hours in household chores was observed in the next 40 years, at 20 hours. Between 1960 and 2019, this figure decreased steadily to 10 hours by 2019.
