The given diagram compares the total population in the age group of 65 and over across three distinct nations over a 20-year period, and predictions for 2030.
Overall, the proportions of the elderly in all the surveyed countries are expected to rise, while the rate of people aging above 65 in Germany outnumbered those in the other countries, and is predicted to do so in the future.
Upon examining the data, an upward trend is projected to be seen in the percentages of the elderly in Canada and the UK. Specifically, the proportion of population aged above 65 in the UK initially made up just nearly 15% of its total residents, which was roughly 5 million higher than that of Canada. In the next 20 years, both Canada and UK witnessed an increase in their population shares, with approximately 15% of the citizens in the age of 65 and over residing in Canada and a roughly 6% higher figure for the latter. Notably, anticipations indicate a subsequent growth in the percentages of Canada and the UK, which are expected to surged to a peak of about 22% and 19%, respectively.
Taking a glance at Germany, around 15% of the total population of this nation, which was the highest rate among all the surveyed countries, belonged to the above 65 age group in the year of 2000. Additionally, the figure for Germany is projected to rise slightly to almost 26% and still remain the country with the highest rate of residents over 65 years old.
