Final answer:
False. The statement is not accurate because the specific number of young adults between the ages of 18-34 who obtained coverage through the marketplace is not mentioned.
Step-by-step explanation:
False. The statement that 2.2 million people who obtained coverage through the market place during the initial open enrollment period were young adults between the ages of 18-34 is not accurate.
According to the information provided, the 2016 U.S. Department of Health and Human Services estimates that the number of uninsured people in the US fell from 20.3% in 2012 to 11.5% in 2016, with 20 million Americans gaining coverage under the ACA. However, the specific number of young adults between the ages of 18-34 who obtained coverage through the marketplace is not mentioned.
Therefore, it is not possible to confirm the accuracy of the statement.
