Global Aging Pattern in 9 Graphs

The world is aging rapidly. The global population was 6,514.33 million in 2005. This figure increased to 7,259.69 million in 2014. The global population grew at a compound annual growth rate (CAGR) of 1.21% in this ten-year period. In the same time frame, the geriatric population (people of ages 65 years and over) grew from 473.93 million in 2005 to 588.13 million in 2014, at a CAGR of 2.43% – almost exactly double that of the overall population. The proportion of geriatric population to the total population increased from 7.28% in 2005 to 8.10% in 2014, at a CAGR of 1.20%. This may not seem like a large growth rate, but it’s important to contrast it with the other segments – the proportion of the non-geriatric population segment decreased at a rate of 0.1% every year in the same timeframe. Increasing lifespan and improved access to medical care are important reasons for the changing population structure. The evolving population structures are going weigh-in on the political and social conversations in all nations. Appropriate and adequate aged care structures are going to be an important part of the social support functions of all nations.

Between 2005 and 2014, the growth rate of the geriatric population was double that of the overall population. The proportion of the geriatric population segment increased from 7.28% in 2005 to 8.10% in 2014. Rapid aging is a common feature of the populations of most nations. However, the proportion and rates are vastly different.

China, India, and the U.S. had the largest populations in the 2014. The combined population of these big-3 nations was 41% of the global population.

However, the growth rates of the population in these three nations in vastly different. The population growth rate for India between 2005 and 2014 was 1.39% – higher than the global average of 1.21%. The growth rates for U.S. and China were 0.85% and 0.51% respectively.

The global geriatric population too had a similar profile as that of the global population – China, India, and U.S. are the top-3 nations with the highest number of people of ages 65 years and over.

However, the profile of the growth rates of the geriatric population was substantially different. Of the top-3 nation with the largest populations, India had the highest growth rate for its geriatric population. However, the growth rates of the geriatric population in China and U.S. too are higher than the global average. This indicates a higher disparity in the growth rates of the geriatric and overall population for these two nations. They are aging more rapidly than India.

In terms of proportion, Japan has the highest percentage people of ages 65 years and over. Close of 26% of its population was over the age of 64 years in 2014. Of the big-3, India had the lowest proportion. Just 5.49% of Indians were over the over the age of 64 years in 2014 – much lower than the global average of 8.10%. On the other hand, 14.39% of the population of the U.S. was over the age of 64 years in 2014.

However, the proportion is rapidly chaining in all three nations – the growth rates of the geriatric population as a proportion of the total population were higher than the global average for all of the big-3 nations, indicating rapid and substantial shit in their population structures.
