This early look at the growth in the individual or nongroup market during the first three months of 2014 uses first quarter enrollment data submitted by insurance companies to state regulators to estimate the size of the market at the end of March. It includes both on and off exchange enrollment and is net of any people leaving the market (whether through plan cancellations or general churn in the market). It does not include the surge of enrollment that occurred toward the end of the open enrollment period as those enrollees most likely began their coverage in April or May.
The Kaiser Health Policy News Index is designed to help journalists and policymakers understand which health policy-related news stories Americans are paying attention to, and what the public understands about health policy issues covered in the news.

Most Common Reason for Remaining Uninsured is Not Being Able to Find an Affordable Plan; Just 7 Percent Would Rather Pay a Fine than Pay for Coverage As the Supreme Court Considers Challenge, a Majority Supports the Law's Requirements for Contraceptive Coverage, Including for Employers with Religious Objections Despite the news that 8 million people…
Despite the news that 8 million people have signed up for health insurance through the ACA’s new marketplaces, the April Kaiser Health Tracking Poll finds no change in overall opinion of the law since last month . The most common reason for remaining uninsured is not being able to find an affordable plan. Also, a majority of the public supports the ACA’s requirement that private health insurance plans cover the full cost of birth control and believes that for-profit companies should be subject to this requirement even if their owners object to birth control on religious grounds.
