Healthcare & Medical Industry in the United States
The Healthcare & Medical industry in the United States is one of the largest, most important, and fastest-growing sectors of the American economy. It includes hospitals, physicians, clinics, nursing and residential care facilities, pharmacies, medical laboratories, biotechnology companies, pharmaceutical manufacturers, medical-device companies, health insurers, home healthcare providers, telehealth businesses, healthcare technology companies, and a wide range of professional and support services.
The sector is also one of the largest sources of employment in the United States. According to the U.S. Bureau of Labor Statistics (BLS), the broader healthcare and social assistance sector employed approximately 23.7 million people in 2024 and is projected to reach approximately 25.7 million jobs by 2034. Employment in the sector is projected to increase by 8.4%, making healthcare and social assistance the fastest-growing of the major U.S. economic sectors during the 2024–2034 period.
Healthcare is also exceptionally important in terms of economic output and consumer spending. According to the Centers for Medicare & Medicaid Services (CMS), U.S. national healthcare expenditures reached $5.3 trillion in 2024, equivalent to $15,474 per person and approximately 18.0% of U.S. GDP.
Overview of the U.S. Healthcare Industry
The American healthcare system is a complex combination of private companies, government programs, nonprofit organizations, healthcare professionals, insurers, research institutions, and consumers.
Unlike countries that operate predominantly through a single national healthcare system, the United States uses a mixed system in which people receive healthcare through a combination of employer-sponsored insurance, individually purchased insurance, government programs, direct payments, and other funding mechanisms.
Major government healthcare programs include:
- Medicare
- Medicaid
- Children’s Health Insurance Program (CHIP)
- Veterans health programs
- Military healthcare programs
- Public health programs
Private health insurance also plays a major role. Employer-sponsored insurance is particularly important, while individuals can purchase coverage through private insurers and government-regulated marketplaces.
In 2024, private health insurance accounted for approximately $1.64 trillion, or 31% of national health expenditures. Medicare accounted for approximately $1.12 trillion, Medicaid approximately $932 billion, and out-of-pocket spending approximately $557 billion.
