(CNSNews.com) -- A new survey shows that Americans view "immigration/illegal aliens" as the number one problem facing the United States this month. It was cited by 21% of Americans as the most important problem and this percentage is up from 13% in October, an increase of 8 percentage points.

In the survey, Gallup asked Americans to mention the problems they view as most important. Gallup reported the answers for problems cited by at least 3% of respondents.

At the top of the list was "immigration/illegal aliens" at 21%.

"Dissatisfaction with government/Poor leadership" came in second at 18%.

"Healthcare" was third at 11% and "unifying the country" was tied at fourth and fifth with "Race relations/Racism," both at 9%.

"Unemployment/jobs" was at the bottom of the list, tied with "Education," at 3%.

Neither climate change nor gun control made the list.

"Americans are more likely to name immigration as the top problem facing the U.S. in November than they were in October -- it surged to 21% from 13%," said Gallup. "Mentions of healthcare as the most pressing issue also increased, from 6% last month to the current 11%."

"The current 21% who cite immigration or illegal aliens is about as high as the record 22% Gallup recorded in July," reported Gallup. "The issue's move to the top of the list comes after a large group of Central American immigrants, widely described in the media as a caravan, formed last month with intentions of crossing the U.S. border."

"It became politicized by President Donald Trump, who declared the caravan a 'national emergency' and sent 5,000 troops to the border to try to prevent illegal entries," said the survey firm.

Gallup further reported, "Currently, 35% of Americans are satisfied with the way things are going in the U.S. -- consistent with the 33% to 38% range for this issue since May. Twin 38% readings, recorded in June and October, marked a 12-year high for the measure."

Gallup conducted its survey Nov. 1-11, prior to and after the Nov. 6 midterm elections.
