Final answer:
The top 1% of healthcare consumers are responsible for approximately 20% of the overall healthcare expenses, reflecting the high concentration of healthcare expenditure within a small segment of the population.
Step-by-step explanation:
The top 1% of consumers in healthcare spend approximately 20% of overall healthcare expenses. Healthcare expenditure is highly concentrated, with a small fraction of the population accounting for a significant portion of total spending. Notably, healthcare spending also tends to increase with age, reflecting higher health-related needs among older populations. Given the expected growth in healthcare spending, it's crucial to understand how a minority of consumers can account for such a sizable chunk of healthcare costs.
