One possible factor in the growing popularity of exchange-based plans versus other sources is improvements made to the federal exchange website to correct a wide array of technical issues that plagued the site. Another factor may be that previously uninsured Americans who now have health insurance for 2014 had other options, such as insurance through an employer or signing up on a spouse’s or parent’s plan. Those options may not be as available to those who remain uninsured.

The latest results are based on Jan. 2-28 Gallup Daily tracking interviews with more than 1,500 Americans who currently do not have health insurance.

Currently, 53% of all uninsured Americans say they plan to get insurance, while 38% say they are more likely to pay the fine the government will assess most Americans who lack health insurance.
