The given line chars provide information about the relation between having various household machines and the amount of housework hours in families of one nation over a century, starting from 1920.
From a general perspective, there was an upward trend for the proportions of families having washing machine, freezer, hoover, whereas the figure for housework was negatively correlated. The percentages if refrigerator and vacuum cleaner share the highest position in the period shown.
In the year 1920, the quantity of housework hours stood at 50 and began to decrease moderately to 20, about 2 times smaller than that for the beginning after 40 years. From the year 1960 onwards, the time for housework continued its downward trend steadily and slightly followed by reach the bottom at 10 in the year 2019
As it can be seen from the other chart, the figures for washing machine, hoover, started at 40 and 30 in turn. The year 1960 marks the point at which the figure for vacuum cleaner overtook that for washing machine and continued to increase significantly to reach the plateau at 100 in the year 200 onwards. However, the rate of household having freezer reached the highest position in the year 1980, 10 years sooner than that for hoover, after rocketing from the zero start to 90 in the year 1960
