The Centers for Medicare and Medicaid Services (CMS) provides comprehensive National Health Expenditure (NHE) data that reveals critical insights into healthcare spending patterns across the United States. This analysis examines how American health spending has evolved from 1970 through 2024, highlighting the economic forces driving growth and the transformative impact of recent events on healthcare costs.
Historical Growth in National Health Expenditure
The trajectory of U.S. health spending demonstrates remarkable expansion over five decades. In 1970, total health expenditures stood at $74.1 billion. By the turn of the millennium in 2000, this figure had surged to approximately $1.4 trillion. The growth continued dramatically, with 2024 witnessing nearly $5.3 trillion in total health spending—more than triple the 2000 amount.
This sustained increase reflects both population growth and rising healthcare costs per person. The data encompasses all healthcare-related activities, including insurance administration, health research initiatives, public health programs, and direct medical services funded through both public and private sources.
Recent Spending Acceleration Patterns
The COVID-19 pandemic created unprecedented disruption in healthcare spending trends. During 2020, the first year of the pandemic, health expenditures accelerated by 10.5% compared to 2019 levels. This sharp increase reflected emergency response costs, treatment expenses, and healthcare system adaptations.
More recent years show continued robust growth. Health spending increased 7.2% from 2023 to 2024, closely matching the 7.4% growth observed from 2022 to 2023. Both years significantly exceeded the 4.8% increase recorded from 2021 to 2022. Importantly, the 2023-2024 growth rate substantially surpasses the average annual growth rate of 4.2% that characterized the 2010s decade.
Inflation-Adjusted Spending Analysis
Understanding real healthcare cost growth requires accounting for inflation. The analysis presents spending data in both nominal dollar values and constant 2024 dollars, adjusted using the personal consumption expenditures (PCE) index. When adjusted for economy-wide inflation, national health spending increased 4.4% in 2024 compared to the previous year.
The federal actuaries employ an alternative methodology, using healthcare-specific consumer and producer price indices for particular commodities and services. According to the NHE deflator, real national health expenditures grew 4.6% from 2023 to 2024, slightly higher than the PCE-adjusted figure.
Per Capita Health Spending Evolution
Individual healthcare costs have risen dramatically over the past fifty years. On a per capita basis, total health spending—encompassing government programs, private insurance, out-of-pocket expenses, research funding, and infrastructure investments—increased from $353 annually in 1970 to $15,474 in 2024.
When expressed in constant 2024 dollars to eliminate inflation effects, per capita spending grew from $2,208 in 1970 to $15,474 in 2024. This represents a sevenfold increase in real terms, demonstrating that healthcare cost growth has far outpaced general inflation over this period.
Health Spending as Economic Indicator
GDP Percentage Analysis
Health spending’s share of gross domestic product (GDP) reached 18.0% in 2024, representing a slight uptick from 17.7% in 2023. This increase occurred because health expenditures grew faster than overall economic output during the year.
The healthcare sector’s economic footprint peaked at 19.7% of GDP in 2020 during the pandemic, when simultaneous increases in health spending and declining GDP created an unprecedented spike. As the economy recovered, total national health expenditures as a GDP share declined through 2022.
Post-Pandemic Stabilization
Since 2022, health spending has stabilized at levels comparable to pre-pandemic proportions. While growth rates remain elevated compared to the previous decade, the healthcare sector’s share of the economy has returned to more sustainable levels following the COVID-19 disruption.
The long-term trend shows healthcare consistently claiming a growing portion of economic activity, though recent decades witnessed slower growth rates than earlier periods. Nevertheless, health spending growth has historically exceeded GDP growth, reflecting healthcare’s expanding role in American economic life.
