Chronic illness is no longer a background health issue. In 2021, 133 million Americans, nearly 40% of adults, lived with at least one chronic condition, and those conditions drive 90% of the nation’s $4.1 trillion in annual healthcare spending. The patterns behind the totals are where it gets striking, from 30% higher hypertension in Black Americans to diabetes costs of $327 billion each year.
Key Takeaways
- In the US, adults aged 65+ with chronic conditions: 85%, driving Medicare costs
- Black Americans have 30% higher hypertension prevalence than whites
- Women are 2-3 times more likely to develop rheumatoid arthritis
