More than a billion people were already aged 60 or over in 2019, but projections suggest the world is on track to reach 1.4 billion by 2030. The ripple effects show up everywhere, from health budgets to care jobs, and the burden is falling most heavily on countries with the fewest resources. Grab the full picture by looking at how dependency ratios, spending shares, and long term care markets are shifting side by side.
Key Takeaways
- 1.0 billion people are aged 60+ worldwide in 2019, with the number projected to reach 1.4 billion by 2030
- 20.0% of Germany’s population is aged 65+ (2023)
- 75% of the world’s older people live in low- and middle-income countries
- In 2021, Canada’s old-age dependency ratio was 24.7 (65+ per 100 15–64)
- By 2050, South Korea is projected to have an old-age dependency ratio above 70
- 5.2% of GDP is spent on health care in OECD countries, on average, and health spending is projected to keep rising with population ageing
- Medicare spending is projected to reach $10.2 trillion from 2024 to 2033 (trustees’ projections)
- In 2022, the UK’s health and social care spending increased to £335.0 billion
- Dementia affects about 10% of people aged 65+
- In OECD countries, the share of jobs in “health and social work” was 9.8% in 2022
- 10.8% of the world’s population was aged 65+ in 2021
- Health spending is projected to increase by 2.0 percentage points of GDP on average in OECD countries by 2060
- Older adults accounted for 34% of all deaths globally in 2021 (age 70+ share)
- Global healthcare spending is projected to reach $10.0 trillion by 2022 (with aging as a key driver)
- Hypertension prevalence was 66.1% among adults aged 65+ in the United States in 2017–2018
As populations age, health and long term care spending is rising worldwide, straining services across low and high income countries.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
