The findings come from Pew Research in its latest revelation from a study of the religious beliefs and practices of teens and their parents.
Among 13- to 17-year-old teenagers, 45 percent believe many religions may be true, far outpacing the 31 percent who believe only one religion is true. A much smaller portion, 15 percent, believe there is little to no truth in any religion, and 8 percent believe no religion is true.
Pew included a teenager and a parent from each household surveyed, and found that the religious beliefs of teenagers largely mirrored those of their parents.
The largest portion, 47 percent, of parents included in the study said many religions may be true, compared to 33 percent who expressed an exclusivist view of religion, and 19 percent who said there is little or no truth in any religion.
When divided by religious affiliation, evangelical Protestant teenagers registered the largest portion of respondents, 66 percent, who believe in one religion, compared to 28 percent of the subset who believe many religions may be true, Pew said.
Regional differences also hold, with the largest group of teenagers expressing a pluralistic view of religious truth, 61 percent, residing in the Northeast. 41 percent of Southern teens said many religions may be true, 51 percent in the Midwest and 37 percent in the West.
