In 2025, the United States experienced an uninsured rate holding steady at 8%, according to data from the Centers for Disease Control and Prevention (CDC). This period marked the first year of President Donald Trump's second term in office, during which significant changes were made to the healthcare landscape. The overall uninsured population grew by approximately 800,000 people, including 300,000 children, a likely consequence of a rising population in conjunction with sweeping reforms affecting Medicaid, the federal safety-net health program designed for low-income individuals, which some estimates suggest might lead to 10 million additional uninsured individuals over the next decade. As the Trump administration continued its efforts to reshape the healthcare system, the expiration of Affordable Care Act (ACA) subsidies contributed further to the instability within health insurance markets. These subsidies had previously helped reduce premium costs and maintained participation levels in marketplace health programs. Experts predict that around 5 million fewer people are expected to enroll in these plans in 2026 compared to the previous year, indicating a significant drop in coverage. The impact of these policy changes is exacerbated by an ongoing trend of increasing uninsured rates amongst those under 65 years old, a demographic that has often relied on various forms of public and private insurance coverage. Historically, the rise of the uninsured rate in the U.S. has been a troubling trend, particularly from the 1980s through the early 2000s, where the number of uninsured Americans climbed steeply from 12% in 1980 to over 18% by 2010. However, the implementation of the Affordable Care Act in 2010 led to significant reductions in the uninsured rates, bringing it close to 10% by 2016. This rate fluctuated during the Trump administration, eventually settling between 11% and 12%. The COVID-19 pandemic briefly reversed this trend, resulting in an all-time low uninsured rate under 9% in 2023, supported by government policies aiming to preserve coverage amid economic disruptions. As the health landscape continues to evolve in the wake of policy changes, researchers anticipate that the trend of increasing uninsured individuals may return as past measures, particularly those affecting Medicaid and ACA subsidies, take full effect. The implications are significant, both for individuals who may lose coverage and for the overall healthcare system as millions face the prospect of navigating the healthcare landscape without insurance. A particular focus has emerged around the treatment of vulnerable populations, including low-income Americans and children, as the effects of these reforms take shape in the coming years.
