Overall, there was a steady increase in number of households with electrical appliances, whereas the number of hours allocated to housework per week declined drastically, which implies the invesre correlation between two charts.
In 1920 households posessed washing machines and vacuum cleaners amounting to 40% and 30%, respectively. The most importantly there wasn’t any household with a refrigerator.

The percentage of households with washing machines plateaued since 1980s, compared to steady increase by both vacuum cleaners and refrigerators that rached 100% by 2000.
The second chart demonstrates decline in the number of hours spent on churn. Starting from 1920, 50% of time was spent on housework, going forward on timeline there are downward trend, which reached 10% by 2019
