Gallup's confidence poll steady in April A national poll on confidence in the U.S. economy was unchanged March to April, researchers at Gallup said Tuesday. PRINCETON, N.J., May 1 (UPI) -- A national poll on confidence in the U.S. economy was unchanged March to April, researchers at Gallup said Tuesday. The April survey put the Economic Confidence Index at minus 20, which sounds low, but is at the highest level since the firm began its daily tracking of consumer confidence at the start of 2008. The index stood at minus 22 in February and minus 27 in January, Gallup said. Broken down in to component indexes, Gallup said the outlook index has increased by 46 points from minus 59 in August to minus 13 in April. The current conditions component has risen by 20 points, from minus 46 to minus 26. Current results are based on telephone interviews conducted in April with a random sample of 13,642 adults ages 18 and older. Researchers can say with 95 percent confidence the results have a margin of error of plus or minus 1 percentage point.
