The graphs illustrate the changes in ownership of electronic appliances and the amount of time spent on doing housekeeping in households at a single place in the period between 1920 and 2019.
Overall, it can be seen that the percentage of households having electrical devices showed a significant rise over 100 years, while the number of hours devoted to household chores experienced an extensive fall.
Since 1920, the most rapid rise showed the percentage of refrigerator owners, starting from zero percent in 1920 and reaching more than 50% in 1940, and later leading to 100% beginning in 1980. The washing machine’s owners rate also grew expansively from 30% in 1920, extending a half of the population in 1940 and finishing at 100% in 2000. The situation is different when comparing with the percentage of households owning a washing machine. The chart shows a rise from 40% in 1920 to 70% in 1960. Then there was a slight drop to 60% in 1980. After that, the figure kept rising slowly but steadily and reached more than 70% by 2019.
The number of working hours spent on household activities was at its peak in 1920, with fifty hours per week. From that time, the amount faced a rapid decrease to about 15% by 1980. The indicator remained stable for twenty years, and thenceforth slightly dropped to about 10% by 2019.
