The charts depict the changes in the proportion of households owning electrical appliances and time spent doing household chores per week in a nation for a century.
Overall, the number of appliances had increased, whereas the number of housework per week had dropped significantly by 2019.
Initially, in 1920, the percentage of washing machine was more than vacuum cleaner and refrigerator. It was at 40%, whereas vacuum cleaner was at 30% and the refrigerators were not in existence. During the middle period, the number of vacuum cleaner and refrigerator showed rapid increase and by 2019 every household (i.e. 100%) had both appliances. Conversely, the percentage of rise in washing machine was comparatively slower and ended at just over 70% by 2019.
Regarding the time spent on housework per week, it was at 50% in 1920, thereafter fell gradually, and bottomed at 10% in 2019 which was 80% lesser than the beginning.
