IV. Sample essay for Mixed Charts IELTS Writing Task 1
Task: The charts below show the changes in ownership of electrical appliances and the amount of time spent doing housework in households in one country between 1920 and 2019. Summarize the information by selecting and reporting the main features, and make comparisons where relevant.
Looking at the first graph, it is clear that the proportion of households possessing these devices increased over time, with every family having both refrigerators and vacuum cleaners by 2019. The most significant change overall was witnessed between 1920 and 1960; whereas the proportion of households with fridges rose markedly from almost none to 90%, those of households with washers and households with vacuums increased more modestly, both reaching 70% in 1960. Afterward, ownership of fridges reached 100% in 1980, and in 2000, ownership of washing machines followed. Ownership of vacuum cleaners slightly dipped to about 65% in 1980 before recovering and reaching its peak of 75% in 2019.
Contrasting the trend of electrical appliance possession, the amount of time that people spent doing housework shrank throughout the period. The first 60 years saw the most notable decline, from 50 hours per week in 1920 to 15 hours in 1980. Then, following another 20-year period of stability, the number of weekly housework hours fell further to its lowest point of about 10 in 2019.
