The two charts above are presenting the data related to housework and electrical appliances. In the first chart, we can see that the overall percentages are increasing, which means that there are more and more families holding electrical appliances from 1920 to 2019. Looking at the graph for the refrigerator, we can see that they changed the most rapidly, there was almost 0% of the households that had a fridge in 1920. However, in 1980, all the families in this country had a fridge in the house. In addition, there is a weird graph in the first chart, which is the graph of the washing machine. There was a significant drop from 1960 to 1980.
