What was one outcome of the ACA in terms of insurance coverage rates?

One of the key outcomes of the Affordable Care Act (ACA) was the significant decrease in the number of uninsured Americans. The ACA introduced a range of measures designed to make health insurance more accessible and affordable. These included the expansion of Medicaid in various states, the establishment of health insurance marketplaces where individuals could compare and purchase plans, and provisions that aimed to lower costs and eliminate discriminatory practices in insurance coverage.

As a result, millions of Americans who previously lacked access to affordable coverage gained insurance. The ACA not only aimed to enhance the overall quality of healthcare but also to ensure that more individuals and families could obtain health insurance, thus directly contributing to a notable decrease in the uninsured rate across the nation.

The other options do not accurately reflect the outcomes associated with the ACA; for instance, the legislation was aimed at increasing coverage, not decreasing it or leading to less regulation of insurance companies.
