The line graphs illustrate the proportion of electrical appliances owned by households and how many hours were spent for housework per family over the period shown.
From 1920 to 2019, in ownership of electrical appliances, the percentage rose conspicuously while the statistics for hours doing housework reduced gradually. Moreover, both graphs present enormous changes in data over the period between 1920 and 1960.
In 1920, all forms of electrical appliances were recorded at lowest. The proportions of households which owned washing machines, refrigerators and vacuum cleaners were about 40%, 30% and nearly 0%, respectively. On the other hand, 1920 was the time that people spent the highest amount of hours for housework per week with about 50 hours. This number decreased to lowest at nearly 10 hours in 2019, while the figures for three types of electrical appliances reached its peak at more than 70% for washing machines and every house owned refrigerators and vacuum cleaners during this period.
In the first three years, both graphs recorded enormous changes in statistics. All three forms of electrical appliances grew fastest, for instance, refrigerators grew nearly 80% during this period while the number of hours spent doing housework received the largest reduction from 50 hours to 20 hours.
