Band 9: 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 given line graphs represent the statistics of household appliance ownership and the duration of housework in a particular country, from the year 1920 to 2019.

Overall, there has been a significant increase in the ownership of household devices, leading to a notable reduction in the time spent doing household chores.

As per the first graph, the ownership of refrigerators was quite rare in 1920, but it increased drastically since 1930, and by the year 1980, every household owned one. A similar but more gradual trend can be observed with vacuum cleaners, which were owned by just three out of ten households a century ago but are now ubiquitous. The ownership of washing machines also increased from 40% to just over 70% in the past century.

The second line chart indicates a clear relationship between household appliance ownership and the amount of time spent on housework. The average number of hours spent doing household chores dropped significantly from 50 hours per week in 1920 to only 10 hours per week in 2019.
