The graphs below show the age structure of a European country from 1901 to 1981 and a prediction for 2024.Summarize the information by selecting and reporting the main features,and make comparisons where relevant.You should write at least 150 words.

　　Sample Answer

　　The graphs compare the population makeup of one European country every forty years from 1901 to 1981,and the estimated number in 2024.

　　There was a huge increase in the number of people in this country from 38,225,000 in 1901 to 67,180,000 eighty years later,and this upward trend is expected to last through to the year 2024,when the population is estimated at 87,658,000,more than double the 1901 figure.

　　In 1901 and 1941,the population structure in this country was completely the same,with an overwhelming majority of its populationbelow 65,4%between 65 and 85 and only 1%over 85 years old.

　　However,the year 1981 saw a sharp increase in the percentage of the elderly.Altogether,they made up 17%of the total population,whereas the projection for the year 2024 shows that they will continue to grow but less dramatically to 20%of the total population.

　　In summary,changes are taking place not only in the number of people but also in the ages of the people who make up the population in this European country,indicating it is advancing into an aging society.
