The line charts demonstrate the proportion of controlling three types of auto-machines and how many hours people in one country take up to do chores from 1920 to 2019. It is clear that the larger percentage of electrical utilizations are being employed, the less time people make for doing housework per week. According to the first graph, people have gradually taken advantage of appliances using electricity during a century period shown. In 1920, refrigerators were not common in daily lives with nobody using them until 1940, the figure for owning them witnessed a considerable increase to approximately 60%, compared to exactly 60% and 50% for washing machines and vacuum cleaners. For the next 40-year period shown, refrigerators have become the most popular home appliances with 100% residents of this country buying them. After having reached 90%, the percentage of vacuum cleaners that existed over the whole region also soared to 100% and became as standard as refrigerators over the last 30 years. Although the figure for acquiring washing machines dipped to 60% then climbed back and kept increasing from 1960 to 2019, it still got far from that of two other appliances. Looking at the details of the second chart, the number of time that population of this state spent doing chores experienced a significant fall from 50 hours to 20 hours per week during the first 40 years shown, then minimally leveled off year by year and finally came to relatively 10hours per week at the end of the period.
