The image contains two line graphs, the first titled "Percentage of households with electrical appliances (1920-2019)" and the second titled "Number of hours of housework per week, per household (1920-2019)"; both x-axes range from 1920 to 2019 in increments of 20 years, and y-axes vary in scale and units. The first graph depicts 4 lines representing washing machines, refrigerators, vacuum cleaners and electric irons, with data points at 1920:0%, 1940:washing machines 20%, refrigerators 10%, 1960:washing machines 40%, refrigerators 50%, vacuum cleaners and electric irons 10%, 1980:washing machines 60%, refrigerators 90%, vacuum cleaners 20%, electric irons 30%, 2000:washing machines 80%, refrigerators 100%, vacuum cleaners 60%, electric irons 40%, 2019:washing machines 100%, refrigerators 100%, vacuum cleaners 80%, electric irons 70%. The second graph shows a single line for "Hours per week" declining from 1920:50, 1940:40, 1960:30, 1980:20, 2000:10, 2019:<5.
