number of households using electrical tools for housework
The line graphs illustrate the proportion of households using electrical tools for housework and using hours in every family weekly between 1920 and 2019.
It is obvious that the percentage of housewives choosing to use the refrigerator and vacuum cleaner was an upward trend during the research period. In contrast, It was the unstoppable fall in the number of working hours which housewives spent on household chores per week.
As can be seen from the first chart, In 1920 there was no household used refrigerator in their home. However, this number rose rapidly to 100% of households after 80 years and remain stable from 2000. Likewise, the growth of the proportion of vacuum cleaner users was similar to the refrigerator one, but it reaches its top at 100% of housewives in the year 2000 and remains unchanged. Moreover, the percentage of housekeepers chosen to use washing machines was made up the highest at 40% in 1920, which then fluctuated slightly and got over 70% of users in 2019.
At the same time, the amount of time which housewives spent on household chores per week decrease dramatically by 40 hours all over the period.
