Wealthy nations often allocate significant portions of their economies to healthcare, reflecting a commitment to the well-being of their citizens. The United States, a global economic powerhouse, is no exception. However, when we meticulously Compare Country Size in terms of economic strength and health expenditure, the U.S. stands out, not always for the reasons one might expect. This analysis delves into how U.S. health spending compares to other similarly large and affluent OECD (Organization for Economic Co-operation and Development) countries. We leverage data from the OECD Health Statistics database to provide a clear and insightful comparison.
U.S. Health Spending: A Giant Relative to Economic Size
It’s a well-established trend that wealthier countries tend to invest more per capita in healthcare compared to lower-income nations. This is logical as greater economic capacity often translates to better healthcare infrastructure, advanced medical technologies, and broader access to services. However, even within the bracket of high-income countries, the United States’ health expenditure is notably higher. Understanding this disparity requires a nuanced approach, acknowledging that each country operates within its unique political, economic, and social frameworks that inevitably shape its healthcare spending patterns.
To ensure a meaningful comparison, rather than just looking at any OECD country, we focus on nations that are comparable to the U.S. in terms of economic size. We’ve selected OECD countries that, for at least one year in the last decade, have demonstrated above-median national incomes and above-median income per person, using both GDP and median GDP per capita as our metrics for ‘country size’ in economic terms. This approach allows us to compare the U.S. against its true economic peers, providing a more accurate picture of its healthcare spending in a global context.
The Spending Gap: U.S. Outpaces Peer Nations Significantly
In 2022, health expenditures per person in the United States reached a staggering $12,555. This figure isn’t just incrementally higher; it surpasses every other high-income nation by over $4,000. To put this into perspective, the average health spending per person among comparable countries stands at approximately $6,651. This means, on average, other large, wealthy countries spend roughly half the amount per person on health compared to the United States. This significant difference underscores a fundamental divergence in healthcare spending priorities and/or system efficiencies when we compare country size and economic output against healthcare investment.
Recent Trends: Spending Increases Across the Board, But U.S. Growth Moderates
Globally, the trend in healthcare spending is generally upward. Between 2021 and 2022, almost every peer nation witnessed an increase in per capita health spending. The Netherlands was a notable exception, recording a slight decrease of 0.1%. In the U.S., per capita health spending grew by 2.9% during this period. While still an increase, this growth rate was actually smaller than that of most comparable nations. It was, however, higher than the increases seen in Australia (2.4%), Canada (0.7%), and the United Kingdom (0.5%). Belgium experienced the most substantial surge in per capita health spending among countries with available data, with a 9.6% rise.
The 2.9% increase in U.S. per capita health spending in 2022 represents a slight uptick from the 2.4% increase observed between 2020 and 2021. However, it remains considerably lower than the dramatic 9.8% spike recorded from 2019 to 2020, a period heavily influenced by the onset of the COVID-19 pandemic. This suggests a moderation in the growth rate of US healthcare spending in the immediate post-pandemic period compared to some peer nations.

Health Spending as GDP Share: U.S. Still Leads Despite Recent Decline
Looking at health spending as a percentage of Gross Domestic Product (GDP) provides another critical dimension when we compare country size and economic allocation. Over the past half-century, the gap between the U.S. and comparable OECD countries in terms of health spending as a share of the economy has widened significantly. In 1970, the U.S. allocated approximately 6.2% of its GDP to health, a figure comparable to several other wealthy nations (the average for comparable countries was around 4.9% of GDP in 1970). Up until the 1980s, the U.S. was broadly in line with its peers. However, starting in the 1980s, health spending in the U.S. began to escalate at a much faster pace relative to its GDP growth. This divergence has continued, meaning health spending as a proportion of the economy has grown more rapidly in the U.S. than in other economically similar countries.
The COVID-19 pandemic created a unique economic environment, triggering both increased health spending and economic contraction. This resulted in a spike in health spending as a share of GDP in the U.S. and all comparable countries between 2019 and 2020. As economies began to recover, this share has generally decreased. In the U.S., health spending as a share of GDP reached 18.8% in 2020 (up from 16.7% in 2019), before declining to 17.4% in 2021 and further to 16.6% in 2022. Despite these recent decreases, the U.S.’s health spending as a percentage of GDP remains substantially higher than that of its peer countries, highlighting a continued disproportionate allocation of economic resources to healthcare.
Long-Term Growth Trends: U.S. Growth Historically Faster
While the U.S. has consistently exhibited higher average health spending, the growth dynamics have shifted over time when compared to other nations. Historically, the 1980s marked a period of accelerated growth in per capita health expenditures in the U.S. The average annual growth rate during the 1980s in the U.S. was a striking 10.0%, significantly exceeding the average of 7.3% for comparable countries.
Examining 5-year growth rates provides a more granular view. During the period 2005-2010, the U.S. experienced an average annual health spending growth rate of 4.1%, a slowdown from the 7.2% in the preceding five years. Comparable countries also saw a deceleration in health spending growth, averaging 4.5% annual growth during 2005-2010, down from 5.3% during 2000-2005. In the five years leading up to the COVID-19 pandemic (2015-2020), the U.S.’s growth in per capita health spending again outpaced the average for comparable countries (5.0% versus 3.6%). However, the annual growth rate for comparable countries surged between 2020 and 2022 to 7.0%, while the U.S. saw a more modest increase of 2.7% during the same period. This recent shift suggests a potential convergence or even a temporary reversal in the historical trend of faster health spending growth in the U.S. compared to its economic peers.
Conclusion: Understanding the U.S. Healthcare Spending Landscape
Comparing country size, particularly in terms of economic wealth, reveals that the United States remains a significant outlier in healthcare spending among high-income OECD nations. While recent data indicates a moderation in spending growth and a slight decrease in health spending as a share of GDP, the overall level of expenditure, both per capita and as a proportion of the economy, continues to dwarf that of comparable countries. Understanding the underlying factors driving this persistent gap is crucial for policymakers and stakeholders seeking to address healthcare costs and improve the value derived from healthcare investments in the U.S. Further research and analysis are needed to explore the systemic differences that contribute to these disparities and to identify potential pathways towards more efficient and equitable healthcare spending.
