Aging is reshaping demographics and budgets fast, and it is showing up in both health outcomes and new markets. By 2050, dementia alone is projected to reach 139 million people, while global health spending is expected to climb to $20 trillion, with aging as a major driver. This post pulls together global aging population statistics to show how quickly the shift is happening, from living arrangements and disability-adjusted life years to long term care and assistive technology.
Key Takeaways
- 771 million people aged 65+ worldwide in 2022, making up about 10% of the global population
- The UN projects that by 2100 the global population aged 65+ will reach about 2.5 billion (World Population Prospects 2022)
- In 2019, about 16% of people aged 60+ lived alone in many high-income countries (OECD Health at a Glance 2021, living alone by age)
- By 2030, the world is projected to have 82 million more adults aged 65+ than in 2020
- By 2050, the number of people with dementia is projected to grow to 139 million
- In 2022, global healthy life expectancy at birth was 63.1 years, declining with disability increases in older ages
- In 2019, the global age dependency ratio (population aged 65+/working-age 15–64) was 28.8
- Between 2010 and 2021, global long-term care demand increased due to aging, with the number of persons aged 80+ rising from 71 million to 132 million
- In 2019, 60% of global disease burden (DALYs) was attributable to noncommunicable diseases, which increase with age
- In 2022, there were 28.2 million cancer cases worldwide, with risk rising substantially with age
- In 2019, 14.9 million deaths were attributable to chronic kidney disease (CKD)
- In 2021, the global market for home care services was valued at $349 billion and is projected to grow
- In 2023, the global senior housing market was valued at $278.5 billion
- In 2023, the global medical device market size was $526.2 billion, with demand supported by aging populations
- In 2022, 28% of US adults aged 65+ had used patient portals
By 2100, the world’s 65 plus population will soar, reshaping health, long term care, and costs worldwide.
