Story Highlights

The economy, government most commonly named problems
More Americans say immigration top problem than in October
Republicans more likely than Democrats to name immigration
WASHINGTON, D.C. -- The economy in general and government are the issues Americans are most likely to name as the most important problems facing the country in November. These are followed closely by mentions of immigration and unemployment.

Recent Trends in Top Four "Most Important" U.S. Problems

Government, unemployment and the economy in general have ranked among the most frequently named problems since the beginning of the year. Mentions of immigration increased sharply in July, in response to a large wave of young immigrants crossing the U.S.-Mexico border. Mentions dipped from 12% in September to 7% in October, perhaps because the issue was overshadowed by the Ebola crisis. However, immigration is now back up to 13%.

Mentions of disease, and Ebola specifically, rose to 5% in October, debuting on the list of issues that at least 3% of Americans mention. However, in November, 2% mention Ebola, perhaps because they perceive the threat as less severe than it was a month ago.

Recent Trend for Most Important U.S. Problem

As is typically the case, Americans of differing party affiliations often have dissimilar ideas of the most important problem. For example, Republicans and Republican-leaning independents (27%) are more likely than Democrats and Democratic leaners (14%) to list the economy in general. And Republicans are slightly more likely than Democrats to mention immigration.

Party differences are smaller on government dissatisfaction, healthcare and unemployment.

Top Five U.S. Problems, by Party, November 2014

Mentions of immigration increased similarly between October and November for Republicans (from 9% to 16%) and Democrats (from 4% to 10%). Although it is a pressing issue in many Americans' minds, the prospects for government action are unclear. President Barack Obama is discussing executive action on immigration reform and says he is tired of waiting for Congress to act. Some Republicans are pushing for compromise, and party leaders may be waiting for January, when the GOP takes full control of Congress, but have not issued a plan for action on immigration.

Bottom Line

Government and the economy in general continue to be the most commonly cited problems facing the U.S. Mentions of immigration increased in November after a dip in October. During the current "lame duck" session, congressional leaders may be hesitant to act on these issues -- though this would be the last chance to act for members of Congress who were not re-elected. For their part, Republicans may be waiting until January, when their new Senate majority is sworn in.

Americans are more likely to say they want the new Republican Congress rather than Obama to set the nation's course in January. But more than anything, Americans want Congress to fix itself and begin compromising, a view reinforced by Americans' continuing to name the government itself as the most important problem facing the nation.
