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

The presented line graph illustrates the transformation of ownerships of different electrical equipment and how long they were used for domestic purposes in one particular country from 1920 to 2019.

Overall

, it can be seen apparently that all types of electric appliances experienced an upward trend throughout the period,

whereas

there was a downward trend in the number of

hours

doing the housework.

According to

the period of work, people spent their time in household activities for 50

hours

per week in the initial year,

then

the figure decreased significantly by more than half to 20

hours

in the next four decades.

Subsequently

, the figure continually fell to 10

hours

, in 2019. Turning to the first graph, a washing machine had 40% of households possessed

this

power tool, in 1920, before the number increased continually to 70% forty years later. Afterwards, it dropped slightly to around 65%, in 1980,

then

rose to just above 70% in the final year. Meanwhile, there was only 30% for vacuum cleaners in the beginning, which eventually climbed sharply to a peak and steadily remained over the period.

Additionally

, the refrigerator had nearly 0% in the first year

then

went up dramatically to 90%, in 1960, before rising gradually to 100% and stayed at

this

level until the end.
