The charts below show the change in ownerships of electrical appliances and amount of time spent doing housework in housholds in oun country between 1920 to 2019.

The first line graph illustrates the percentage of

households

equipped with electrical

appliances

between 1920 and 2019,

while

the second graph shows the number of

hours

spent on house chores per week during the same period.

adoption

of

household

electric

appliances

over the years. By 1980, refrigerators reached near-full

adoption

, with almost 100% of

households

owning one. Vacuum cleaner usage followed a similar trend, reaching 100%

by 2000.

owned a washing machine.

, the number of

hours

spent on housework saw a linear decline throughout the same period. In 1920,

households

spent approximately 50

hours

per week on chores, but

this

figure dropped steadily over the years, reaching about 10

hours

per week by 2019. The increasing

adoption

of

household

appliances

, which reduce the time and effort required for cleaning and other tasks, is likely a key factor behind

dramatic 75% reduction in housework

hours

. In conclusion, as the

adoption

of electric

appliances

grew over time, the number of

hours

spent on

household

chores fell significantly.
