The charts below show the changes in ownership of electric appliances and amount of time spend doing housework in household in one country between 1920 and 2019.

The line graphs demonstrate how people changed the electrical appliances they possess, and how much time they consumed on the residences they lived in a country over the period of 99 years.

Overall

, it is apparent that all three household devices were in the upward trend,

while

refrigerators and vacuum cleaners were the major ones people were likely to own.

Moreover

, people used to spend more time on house chores at the beginning of the term rather than

at the end

.

First,

in spite of the fact that fridges were not almost purchased by dwellers in 1920, the percentage of them rose significantly in 1940 to over 50 per cent. It followed by a reasonable increase by 1980 which remained stable until 2019, the quantity of which was the same with that of vacuum cleaners.

Furthermore

, the purchase of washing machines doubled notably by almost 40 per cent in 2019, with slight ups and downs though. Turning to the hours spent on housework, it is clearly seen that residents would do more chores in 1920 in a week (50 h), which lessened crucially by 30 in 1940. In the following 2 decades that number declined by approximately 5 hours, despite the unchanged condition in the following 20 years. Time allocated to domestic chores saw a moderate drop to 10 hours in 2019
