percentages of electrical appliances in a given country from 1920 to 2019 and the results on housework undertaken per week. Looking from an

overall

perspective, it is readily apparent that all electrical appliances became more popular,

in particular

refrigerators and vacuum cleaners. The total time spent doing housework has

also

declined steadily and dramatically in the

last

one hundred years. Refrigerators witnessed the most significant rise, beginning at just over 0% in 1920, surging to more than 50% by 1950, and

then

continuing to rise steadily until plateauing at 100% around 1980. Vacuum cleaners started higher at 30% and

then

rose by precisely 20% every 20 years until 1960 when growth tapered and ownership ultimately reached 100% by 1980.

In contrast

, proportions for washing machines began at 40%, climbed to 70% by 1960,

then

fell slightly, and recovered to finish the period at just above 70%. The result for housework was that time spent washing clothes, preparing meals, and cleaning fell steadily from 50 hours a week in 1920 to 20 by 1960. After that, the decline was more gradual, reaching slightly above 10 hours by 2019.
