The charts below show the changes in ownership of electrical appliances and amount of time spent doing housework in households in one country between 1920 and 2019

The given line charts illustrate the proportion of households using electrical appliances (Washing machines, refrigerators and vacuum cleaners) and the total time spent doing housework in one country from 1920 to 2019.

the proportion of vacuum cleaners and washing machine ownership were far higher, accounting for 30% and 40% respectively.

Moreover

, the figure for vacuum cleaners increased by 20% every twenty years from 1920 to 1980 before levelling out at 100% since 2000. There was tremendous growth in the ownership of refrigerators as it had already reached 90% in 1960 before hitting 100% in the next 20 years and remained stable.

In addition

, the figure for washing machines seems to gradually increase before minimally dropping to roughly 65% in 1980 but soon went up in the next 39 years.

Due to

the rise of electrical appliances, the number of time needed for housework declined. Every household required 50 hours per week for washing clothes, preparing meals and cleaning, but the figure dramatically fell to 20% in 1960. Since

then

, the amount of time slowly decreased and hit a low of approximately 10% in 2019.
