The given charts illustrate the changes in ownership of electrical appliances as well as the amount of time spent doing housework in households in a single country from 1920 to 2019. The figures for appliance ownership are shown in percentages, while housework is measured in hours per week.
Considering the first chart, the proportion of households owning a washing machine in 1920 was about 40%. This figure increased gradually over the period and reached approximately 70% by 2019, despite some fluctuations in between. In contrast, ownership of vacuum cleaners began at a relatively low level of around 30% and rose steadily, becoming the most commonly owned appliance by the final year.
Turning to the second chart, it depicts the number of hours spent on household work per week. In 1920, households spent the highest amount of time, at about 50 hours per week. This figure then showed a consistent downward trend, falling to around 20 hours in 1960. Furthermore, in the following years up to 2019, the time spent on housework declined further and stabilised at approximately 10 hours per week.
Overall, ownership of household appliances increased significantly over the years, particularly refrigerators and vacuum cleaners, while the amount of time spent on housework per household decreased steadily throughout the period.
