The charts below show changes in the age structure of the population of a European country between 1901 and 1981 and a prediction for 2021

The given bar charts illustrate the change in age demographics in a European country during a period commencing in 1901 and ending in 1981, with an additional  projection for 2021.

Overall

, it is rapidly apparent that people aged less than 65 years old account for the vast majority of the

population

in

this

country.

Besides

this

, as shown in the pie charts from 1941 onward, the

population

of elder citizens in

this

country has been growing and will continue to grow. In 1901, elderly individuals accounted for only 1% of the

population

; in the subsequent 40 years,

this

figure remained the same.

However

, from 1941 to 1981, the proportion of

this

age group experienced a four-fold increase, and predictions show

this

number is going to climb to 6% by 2021. The proportion of people 65 to 85 years old significantly increased, from only being responsible for 4% of the

population

to 13% in 4%, and predictions show

this

growth will continue.

In contrast

, people aged less than 65 witnessed a substantial decline, from constituting 95% of the total in 1901 and 1945 to just 83% in 1981.
