WASHINGTON, D.C. -- The U.S. uninsured rate is 16.1% so far in January, modestly down from 17.3% in December after the Affordable Care Act's requirement for Americans to have health insurance took effect on Jan. 1. The percentage of uninsured adults aged 18 and older for Jan. 2-19 is slightly lower than what Gallup has measured in any month since December 2012.

These data are based on over 9,000 interviews with American adults collected Jan. 2-19, 2014, as part of the Gallup-Healthways Well-Being Index. This is a preliminary snapshot of the uninsured rate in January 2014, after several provisions of the Affordable Care Act, commonly known as "Obamacare," took effect. The long-term impact of the Affordable Care Act on the uninsured will take months to determine.

Uninsured Rate Drops Most Among Unemployed, Nonwhites

The uninsured rate so far in January has declined more among those who are unemployed than it has among those who are employed. The unemployed remain the subgroup with the highest uninsured rate at 34.1%, but the initial decline among this group suggests the healthcare law may be working as intended for unemployed adults. Additionally, the uninsured rate has fallen more among nonwhites than whites. The uninsured rate among nonwhites so far in January is 26.5%, compared with 29.1% in December 2013.

These preliminary results indicate that, so far, uninsured rates have not declined disproportionately among younger Americans, who continue to be more likely to be uninsured than older Americans.

Implications

Preliminary results from the first 19 days of January show the U.S. uninsured rate has modestly declined since the health insurance mandate went into effect at the beginning of the year. The uninsured rate has fluctuated at other points over the past several years, 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.

Still, with only 2.1 million Americans newly enrolled in plans through the exchanges as of Dec. 28, 2013, the Obama administration and other proponents of the new healthcare law have a long way to go in hopes of reaching the goal of increasing the number of Americans who have health coverage.

Gallup will continue to track the U.S. uninsured rate in the weeks and months ahead.
