After 20 years, all these machines were used above half of the population. Although these were common in the next 40 years, there has been a change in the usage of each. While Refrigerator showed a high demand during the succeeding years to reach the use from 70% in 1960 to 100% in 2017, washing equipment showed fluctuations after 60 years at almost 62% and then showed a gradual increase at almost 80% during the end of the year. Vacuum cleaner, however, showed a steady increase from 30% to 100% throughout these years.
On the other hand, house worls such as washing clothes, cooking and cleaning were initially done by the households since the limited supply of machineries. As technology developed, man work was carried out by machines which can be clearly seen at 50% in 1920 which drastically lowered to 20% in 1960 followed by a gradually decrease reaching at 10% in 2019.
