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 line charts compare the proportion of households with three different electrical appliances—washing machines, refrigerators, and vacuum cleaners—as well as the number of hours spent on housework from 1920 to 2019.

It is clear that the ownership of all three electrical appliances steadily increased over the 99-year period, with refrigerators experiencing the most significant growth. Additionally, the time spent on housework dramatically decreased from 1920 to 1960 and remained relatively stable after 1960.

From 1920 to 1960, the usage of washing machines and vacuum cleaners rose steadily from 40% and 30% respectively, reaching the same percentage of households with these electrical appliances at 70%. Meanwhile, the proportion of households with refrigerators grew dramatically from nearly 0% to 90%. Over the following 59 years, both refrigerators and vacuum cleaners peaked at 100% ownership in 2000, while washing machine ownership remained stable at approximately 70%.

In 1920, the number of hours spent on housework per week in each household peaked at 50 hours. Over the next 40 years, this number fell dramatically to 20 hours per week and continues to decline, reaching nearly 10 hours by 2019.
