The pie charts indicate the population make-up of a particular European country every forty years from 1901 to 1981, and the estimated number in 2021.
There was an enormous surge in the total number of people in this country from 38,225,000 in 1901 to 67,180,000 eighty year later, and this upward trend is expected to last to 2021, when the population is predicted more than double the figure in 1901 (with 87,658,000).
The age structure of this country in 1901 and 1941 was completely similar, with the vast majority of its population was below 65 (95%), 4% between 65 and 85, and only 1% over 85 years old. In 1981, however, the percentage of the elderly showed a significant increase, accounting for 17% of the total population. According to the projection for the year 2021, they will continue to grow to 21% (15% for 65-85-year-old, 6% for over 85-year-old).
In summary, not only the number of people of the country but also the ages of the people are changing, and it illustrates a aging society.
