Band 6+: You should spend about 20 minutes on this task. The graph below shows the population of a particular country by age group starting in 1960 and including a forecast to 2040. Summarize the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

As can be seen from the graph, while the majority of the population witnessed a significant and slight decrease from the age 0 to 14 and 15 to 64 respectively across the period and forecasting to be lower for the future, a sharp rise in the number of elderly people was experienced and is expected to continue with the upward trend in the future. It is apparent that the working-age individuals hold the highest percentage of the total in the beginning.

In 1960, residents over 65 years old occupied around 15% of the whole then stabilized after a decade before seeing a remarkable increase, over doubling from 15% to 35% by 2020. Based on the figure, the expectancy ratio goes up gradually until it reaches nearly half of the total population.

With respect to the remaining groups, a constant drop was observed in the rate of 0 to 14-year-old citizens that declined approximately triple in 60 years, therefore, it is believed to fall to 10% in 2040. Similarly, the middle group faced a mild drop after reaching the peak twice in 1970 and 1990, furthermore, the occurring proportion is predicted to plummet to 45%.
