The charts below show the changes in ownership of electrical appliances and amount of time doing housework and households in one country between 1920 and 2019. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The two line graphs give information on the proportion of families owning electrical appliances and the relative amount of time they spent doing housework in a 100-year time frame (1920-2019). From an

overall

perspective, it is readily apparent that all electrical appliances became more popular, particularly refrigerators and vacuum cleaners,

while

the total hours spent doing housework

also

decreased steadily and dramatically in the

last

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

then

continuing to grow 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

, percentages 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 dropped steadily from 50 hours a week in 1920 to 20 by 1960. After that, the decline was more gradual, reaching above 10 hours by 2019.
