Almost six in 10, or 57 percent, say the country has not improved its disaster preparations, according to the survey by the nonpartisan Pew Research Center. Roughly equal numbers of Democrats, Republicans and independents share that view.
Just 38 percent said the country is more ready than it was.
The poll also found that nearly 7 in 10, or 69 percent, think progress has been made rebuilding New Orleans and the Gulf.
People in the South - which includes Gulf Coast states - feel most strongly about it, with 75 percent saying progress has been made. In other regions, a combined 66 percent see progress.
Democrats were less convinced than Republicans and independents, with 63 percent of them saying reconstruction has moved ahead.
Pew conducted the poll from Aug. 19-22, interviewing 1,003 randomly chosen adults by telephone, including those on landlines and cell phones. The margin of sampling error was plus or minus 4 percentage points.
