From CNBC:
There are now 49 million people without health insurance in the United States, according to the U.S. Census Bureau.
Under the Affordable Care Act, better known to the public as "Obamacare," more than 30 million people would become eligible to buy subsidized private insurance or receive Medicaid coverage in 2014.
The law requires most Americans to have some form of health insurance - known as the individual mandate. The law stipulates that those who do not acquire health coverage will face a penalty.
