The findings presented are the results of a face-to-face survey conducted from December 17, 2005, to January 20, 2006, by Roper Public Affairs and Media, a part of GfK NOP. Interviews were conducted among a nationwide representative sample of 510 adults age 18-24 in the continental United States. Data were weighted for sample balancing by sex and age. The margin of error for the total sample is +/- percentage points at the 95 percent confidence level. The margin of error for subgroups is higher. Because of rounding, numbers may not total 100 percent.
