Longevity is being reshaped by spending and outcomes, but the split is surprisingly uneven. Global health R&D took 8.0% of health spending in 2021, while total healthcare consumption is far broader, with the US at 6.3% of GDP in 2022 and low-income countries at just 3.6% of global GDP in healthcare in the same period. As the care burden grows with 1.5 billion people aged 65+ projected by 2050, these funding and survival metrics start to reveal where progress is accelerating and where it still lags.
Key Takeaways
- 8.0% global health spending share spent on health R&D in 2021
- $2.7 trillion global long-term care spending in 2019 (latest global estimate widely cited by OECD)
- 6.3% of GDP spent on healthcare in the United States in 2022
- 1.5 billion people aged 65+ worldwide in 2050 projected by UN
- 11.3% share of global population aged 65+ in 2019
- US life expectancy at birth was 77.5 years in 2022 (CDC)
- In-hospital mortality for heart failure was 4.3% in 2022 (AHA/NCDB)
- Cancer 5-year relative survival rate was 67% (US, 2015-2019, NCI SEER)
- Breast cancer 5-year relative survival was 91% (US, 2015-2019, NCI SEER)
- Australia life expectancy at birth was 84.3 years in 2022 (World Bank)
- UK life expectancy at birth was 81.3 years in 2022 (World Bank)
- In the US, 73% of adults have used health information online (Pew Research Center, 2019)
- US FDA approved 77 drug approvals in 2022 (CDER annual report)
- US FDA approved 55 new molecular entities/BLAs in 2021 (FDA CDER)
- Per-capita healthcare spending in Switzerland was $10,381 (current US$) in 2022 (World Bank)
Spending and longevity tech are rising fast, while heart disease, cancer, and dementia still drive major deaths.

Interpretation
Cost Analysis Interpretation
From a Cost Analysis perspective, the sharp disparity in per-capita healthcare spending from Switzerland at $10,381 in 2022 to India at $2,041 in PPP terms, alongside the UK NHS average bed day cost of £485, suggests that the same drug or treatment availability gains can translate into very different system-level costs depending on country spending levels.
