RNA - The monthly Gallup survey conducted September 7-11, shows that 14 percent of respondents list the US economy as the biggest challenge confronted by the nation.
Dissatisfaction with the government retains the second-place spot, with 11 percent of Americans naming it as the leading source of concern.
Several other issues register a notable level of concern, including unemployment at 11 percent and election reform at 8 percent.
Other top concerns for the US include race relations (7%), immigration (6%), terrorism (5%), national security (5%) and national morals and ethics (5%).
The percentage of Americans who name elections or election reform as the greatest US problem has been rising, likely because of the controversies surrounding the two highly unpopular major-party nominees.
Polls taken in the past several months have shown that US presidential nominees Donald Trump and Hillary Clinton were ranked among the most unpopular presidential candidates in America’s history.
In the Gallup poll, 7 percent of Americans name racial issues -- including racism and race relations -- as America's top problem.
Americans' mentions of racism and race relations as the most important problem facing the country has increased amid protests over high-profile incidents of police brutality toward blacks.
