Though issues such as terrorism, healthcare, race relations and immigration have emerged among the top problems in recent polls, government, the economy and unemployment have been the dominant problems listed by Americans for more than a year.
The latest results are from a March 5-8 Gallup poll of 1,025 American adults.
While the ranking of the top two problems is similar to what Gallup found in February, mentions of the economy dropped from 16% to the current 11%. In a separate measure, Americans' confidence in the economy had been dipping further into negative territory in late February and early March, but has been improving in recent days.
The state of U.S. healthcare also became less of a problem to Americans in March, as 7% mention it this month, compared with 10% in February.
The latest poll found that terrorism (6%), the situation in Iraq/ISIS (4%) and national security (4%) also ranked among the most cited problems, illustrating that terrorism concerns are still on many Americans' minds.
Results for this Gallup poll are based on telephone interviews conducted March 5-8, 2015, with a random sample of 1,025 adults, aged 18 and older, living in all 50 U.S. states and the District of Columbia. For results based on the total sample of national adults, the margin of sampling error is ±4 percentage points at the 95% confidence level. All reported margins of sampling error include computed design effects for weighting.
Each sample of national adults includes a minimum quota of 50% cellphone respondents and 50% landline respondents, with additional minimum quotas by time zone within region. Landline and cellular telephone numbers are selected using random-digit-dial methods.
