Healthcare spending in the United States consumed 17.6% of GDP in 2023, making it the single largest sector of the economy. That share is projected to reach 20.3% by 2033, meaning roughly one in every five dollars generated in the country will flow through the healthcare system. This enormous financial footprint shapes nearly every corner of economic life, from the size of your paycheck to what your state can afford to spend on roads and schools.
The Biggest Employment Sector in the Country
Healthcare employed over 17 million people in 2023, making it the largest employment sector in the United States. That figure includes everyone from surgeons and nurses to home health aides, lab technicians, billing specialists, and hospital janitors. In many rural communities, the local hospital or clinic system is the top employer, and its financial health determines whether the town grows or shrinks.
This massive workforce means healthcare acts as an economic stabilizer. During recessions, people still get sick and still need care, so healthcare jobs tend to be more resistant to downturns than jobs in manufacturing, retail, or construction. That resilience keeps consumer spending from falling as far as it otherwise would during economic contractions.
How Health Costs Eat Into Wages
One of the least visible economic effects of rising healthcare spending is what it does to worker paychecks. Between 1999 and 2024, the amount workers contribute toward family health insurance premiums jumped by 308%. Total premiums rose even faster, climbing 342% over the same period. Meanwhile, worker earnings grew by just 119%, and overall inflation rose only 64%. Insurance premiums have increased at roughly three times the rate of earnings since 1999.
This gap matters because employer-sponsored insurance is part of your total compensation. When the cost of covering an employee’s family hits $26,993 per year (the 2025 average), with employers picking up about $20,143 of that, those dollars come from the same budget that could fund raises. Economists have long argued that rising health benefit costs suppress wage growth, effectively redirecting money that workers would otherwise see in their bank accounts. For many middle-income families, the net result is a paycheck that feels stagnant even when the economy is growing.
Pressure on Federal and State Budgets
Medicaid alone accounted for $900.3 billion in total spending during fiscal year 2023, with $619.9 billion coming from the federal government and $280.4 billion from states. Federal Medicaid spending represented 10.3% of all federal outlays that year. Add Medicare, veterans’ healthcare, and subsidies for insurance marketplace plans, and government health programs consume a substantial share of public revenue at every level.
At the state level, the squeeze is even more direct. States spent 15.1% of every dollar they generated on Medicaid in fiscal year 2023, a jump of 2.2 percentage points from the prior year, the largest single-year increase in two decades. In most states, Medicaid is the second-largest budget item after K-12 education. Every additional dollar directed toward Medicaid is a dollar unavailable for transportation, public safety, higher education, or infrastructure. When healthcare costs spike, governors and legislatures face a zero-sum tradeoff that ripples through public services.
The US Spends Far More Than Other Countries
The United States spent over $14,880 per person on healthcare in 2024, compared to an average of roughly $6,000 per person across other wealthy nations in the Organisation for Economic Co-operation and Development. That means the US spends about 2.5 times the OECD average. This gap is not primarily because Americans use more healthcare services. It is largely driven by higher prices for hospital stays, prescription drugs, and physician services.
This spending premium has economic consequences beyond the healthcare system itself. American manufacturers compete against companies in countries where governments cover healthcare or where costs per worker are dramatically lower. Small businesses in the US often cite the cost of providing health insurance as a barrier to hiring. And for individuals, high out-of-pocket costs contribute to medical debt, which can reduce credit access, homeownership rates, and consumer spending in other sectors.
Healthcare as an Engine for Innovation
Not all of this spending is a drag. The healthcare sector is also a significant source of economic growth through research and development. Every dollar the National Institutes of Health spent on research funding in fiscal year 2024 generated $2.56 in economic activity. That year, the NIH awarded $36.94 billion in extramural research funding, which directly and indirectly supported roughly 408,000 jobs and produced $94.58 billion in new economic activity across all 50 states.
Since 2015, NIH-funded research has driven more than $787 billion in cumulative economic activity and supported an average of over 370,000 jobs per year. This federally funded basic research feeds the pipeline for the life sciences, medical technology, and pharmaceutical industries, sectors where the US holds a global competitive edge. Biotech corridors in places like Boston, San Francisco, and the Research Triangle owe much of their economic vitality to this upstream investment. The returns show up as new therapies, new companies, and high-paying jobs in fields that didn’t exist a generation ago.
What the Growth Trajectory Means
Healthcare spending is projected to grow at an average rate of 5.8% annually through 2033, well above the 4.3% average growth rate expected for GDP overall. That widening gap is what pushes healthcare’s share of the economy from 17.6% to 20.3% within a decade. The drivers include an aging population, rising prices for prescription drugs and hospital services, and expanding enrollment in government programs as more baby boomers reach Medicare eligibility.
For households, this trajectory means health insurance premiums and out-of-pocket costs will likely continue outpacing wage growth. For governments, it means healthcare will claim an ever-larger share of tax revenue, intensifying competition with other public priorities. And for the broader economy, it raises a fundamental question: at what point does the sheer size of healthcare spending crowd out investment, consumption, and growth in other sectors? The US is running an experiment no other wealthy nation has attempted, dedicating a fifth of its entire economic output to a single industry, and the answer is still unfolding.
