As the Associated Press reported, the falling uninsured rate would correspond with two to three million people becoming insured. The Obama administration has reported that 2.2 million people had signed up for private coverage through the health care reform law as of Dec. 28. More than 6 million people have also been enrolled in Medicaid since October, and among those, people covered by the program's expansion under Obamacare would have had their coverage start on Jan. 1
Gallup cautioned that it's unclear if the drop is directly correlated with Obamacare's implementation.
"The uninsured rate has fluctuated at other points over the past several years," the firm said, "so it is unclear if this small decline is a reflection of the provisions of the Affordable Care Act that took effect on Jan. 1, or if this is part of a trend based on other reasons."
The poll, conducted from Jan. 2 to Jan. 19, surveyed 9,145 American adults, ages 18 and older.
