The first chart illustrates the proportion of households with three different electrical appliances while the second chart shows the amount of time spent per week on household chores. The data cover the period from 1920 to 2019. Overall, the ownership of electrical appliances increased steadily, whereas the time spent on housework declined significantly.
In 1920, the proportion of households owning washing machines was the highest at 40%, followed by vacuum cleaners at 30%, while refrigerators were owned by a negligible proportion of households. By 1940, the share of households with refrigerators increased dramatically surpassing those for both washing machines and vacuum cleaners. From 1960 onwards, the proportion of households owning vacuum cleaners surpassed those of washing machines. By 2019, the percentage of households equipped with washing machines was the smallest at slightly less than 75%, while an equal proportion of households owned vacuum cleaners and refrigerators.
On the other hand, average number of hours spent on housework(around 50 in 1920) declined steadily by 2019 (only around 10). This data remained almost constant (approximately 10 hours ) since 1980.
