The line graph depicts the percentage of households with electrical appliances and the number of hours of housework per week in households in one country from 1920 to 2019.
An overview of the findings indicates that the refrigerator and vacuum cleaner maintained the highest figure, whereas the washing machine had the lowest figure.
Additionally, the number of hours of housework experienced a downward trend.
In the former line graph, the percentage of households with appliances steadily increased. In 1920, the portion of people using refrigerators increased rapidly from 0% to nearly 100% and remained constant over the period. The uses of the washing machine and vacuum cleaner were started at 30% and 40%, respectively, in 1920, and these lines mixed together at 70% in 1969; after that, the vacuum cleaner climbed up to 100% and held its constant position. Before gradually rising up, the uses of washing machines slightly decreased.
The line chart illustrates a short description of a weekly hour of housework over the shown time. In 1920, people spent 50 hours of housework per week, but it dramatically declined and reached about 10 hours by 2019.
