In this article, we will be covering the 20 countries with the highest age dependency ratio in the world. If you wish to skip our detailed analysis, you can move directly to the 5 Countries with the Highest Age Dependency Ratio in the World.
Age Structures Around the Globe
As reported by UNCTAD, there were 54 children or older people for every 100 individuals of working age in 2022. All of the top 30 countries that recorded the highest age dependency ratios were situated in Africa, with a high child dependency being the primary driver. On the other extreme, economies on the Arabian Peninsula and in the Caribbean had low age dependency ratios.
Generally, age dependency ratios initially tend to decrease before increasing as a larger population approaches an age above 64. This initial decline in the age dependency ratios has occurred in most regions of the world. Age dependency ratios are already increasing in developed economies and have been forecasted to reach 73% by 2050. However, the decrease in age dependency will continue in Africa even after 2050.
The age structure also varies between the developed and developing nations. Developed economies have relatively smaller young age cohorts. The largest age groups in such economies are those aged between 35 and 54 years. On the contrary, developing countries have older age classes smaller than their younger classes.
High Dependencies in Africa: An Analysis
As compared to the rest of the world, Africa’s population is younger. As reported by the US Census Bureau, only 5.6% of Africa’s population was above 60 years of age in 2020, as compared to 23.4% in North America. Although the share of adults in the total population across Africa is less, these adults still account for a high number. In 2020, 18 African countries had more than 1 million people aged above 60. Furthermore, the population over 60 in Sub-Saharan Africa is expected to rise from 50 million in 2020 to 600 million by 2100. This implies that the old-age dependency ratio, the proportion of elderly individuals relative to the working-age population, is set to increase in the region.
Fertility tends to influence the age structure across countries. Many sub-Saharan African countries have high fertility levels which impacts their age structure for instance Uganda has one of the lowest median ages in the world. Tunisia in Northern Africa has witnessed a decline in fertility and hence, the median age in the country is comparatively higher. Low median ages also indicate a higher dependency ratio where the working-age population is relatively younger and the older and younger populations depend on them.
Africa remains subjected to poor health conditions among its adults as compared to high-income and even other low- or middle-income countries since the region allocates a limited share of GDP to health. As reported by the National Bureau of Economic Research, the elderly in Africa tend to be disproportionately impacted by non-communicable conditions since 80% of health budgets go to infectious diseases. Older people in African countries such as Nigeria, Kenya, and Uganda are deprived of accessing healthcare facilities. 30% of the region’s elderly population is a victim of an illness or injury that has halted regular activities including work for them.
Companies Addressing the Elderly’s Disease Burden
Life expectancy as well as the health conditions for the elderly around the world have significantly improved as a result of healthcare companies such as AstraZeneca plc (NASDAQ:AZN), Novo Nordisk A/S (NYSE:NVO), and Pfizer Inc. (NYSE:PFE) making advancements. Let’s take a look at what these companies have been up to.
AstraZeneca (NASDAQ:AZN) is a renowned biopharmaceutical company that operates in more than 100 countries across the world. The company recently made a development in regards to HR-positive breast cancer, the most common breast cancer subtype globally. On March 27, AstraZeneca (NASDAQ:AZN) reported that the Japanese Ministry of Health, Labour, and Welfare (MHLW) has approved its Truqap in combination with Faslodex for adult patients with advanced HR-positive breast cancer. The approval was granted based on a trial that showed that Truqap plus Faslodex decreased the risk of disease progression or death by 50% as compared to Faslodex alone.
Novo Nordisk A/S (NYSE:NVO) is another known global healthcare company that caters to serious chronic diseases. The firm continues to target widespread adult diseases including diabetes through innovation. On March 21, Novo Nordisk A/S (NYSE:NVO) reported that Awiqli has been recommended for approval by the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP). Awiqli is a once-weekly basal insulin icodec that has been made to treat diabetes in adults by covering the basal insulin requirements for a week with a single subcutaneous injection.
Pfizer Inc. (NYSE:PFE) manufactures medicines and vaccines that cater to oncology, cardiology, immunology, and neurology. On February 19, the company reported that VELSIPITY has been given marketing authorization by the European Commission (EC) for the treatment of patients aged 16 years and above in the EU with moderately to severely active ulcerative colitis. Previously, VELSIPITY from Pfizer Inc. (NYSE:PFE) was approved by the U.S. Food and Drug Administration (FDA) for adults with moderately to severely active ulcerative colitis, which is an inflammatory bowel disease.
Now that we have analyzed the age structures around the world and the factors contributing to them, let’s move to the 20 countries with the highest age dependency in the world.
20 Largest Economies in Africa Ranked by PPP
Our Methodology:
In order to compile a list of the 20 countries with the highest age dependency in the world, we sourced data from the World Bank. The age dependency ratio as a percentage of the working population has been selected as our metric. This metric represents the ratio of dependents aged below 15 or above 64 to the working-age population aged between 15 and 64. This represents the proportion of dependents per 100 working-age individuals. The most recent data is available from 2022. Hence, the countries have been ranked in ascending order of their proportion of dependents per 100 working-age population, or their age dependency ratios.
