The provided graphs display the ratio of households in one country with washing machines, refrigerators and vacuum cleaners among with number of hours using them per household from 1920 to 2019 period.
From an overall perspective, it is readily apparent that the total ownership of electrical devices dramatically rise, especially vacuum cleaners and refrigerators. In addition, by the end of the period, the amount of time spend on housekeeping per week collapsed.
The figure for washing machine began the period gradually higher than vacuum cleaner at over 10% which was a trend up until 1960 when their lines crossed. It is worth noticing that after, the latter experienced dramatic shift to 100% usage in 2000, while washing machine ownership fluctuated around 70% up until the end of period.
The table data clearly shows that hours of chores done weekly had steady sharp decrease from 50 in the start of period to 20 in 1960, then mildly dropped by 5 hours in 1980 and didn’t change up until 2000. Similarly, numbers of housework fall by 5 again in the end of period.
