The two charts give us an elaborated visualization of the relationship between the usage of electrical appliances and the number of hours of housework per week. From our observation of the charts, we can safely assume that the relationship is an inverse proportionality.
In the first chart, after the 1920s, the usage of electrical appliances spiked. The usage of refrigerators went from near 0% to a staggering 55% in the year 1940. The growth of other appliances like vacuum cleaners and washing machines was moderate for the first twenty years from 1920 to 1940. The percentage of washing machines remained somewhat similar throughout the decades until 2019; however, the usage of vacuum cleaners increased dramatically. Both vacuum cleaners and refrigerators reached a milestone of 100% by the year 2000 and remained constant until 2019.
The second chart illustrates how the number of housework hours has decreased throughout the decades. We can see the steady decline from fifty hours to twenty hours from 1920 to 1960. After that, the decline slowed down for the next two decades followed by the regular fifteen hours from 1980 to 2000. Then, it again continued the decline until it reached the lowest in 2019, around ten hours.
Analyzing the two charts, we can conclude that the usage of electrical appliances in daily life has drastically reduced the housework hours of every household.
