Nearly six weeks into the U.S. military campaign against Iran, a new Pew Research Center survey finds that higher gas prices are the outcome that concerns Americans the most. But majorities also worry about the United States sending ground troops into Iran, large numbers of military casualties, terrorist attacks on U.S. soil, and the war expanding outside the Middle East.

For this report, we surveyed 3,507 adults from March 23 to 29, 2026. Everyone who took part is a member of the Center’s American Trends Panel. The survey represents the views of the full U.S. adult population.

Here are the survey questions used for this report, the detailed responses and the survey methodology.
