Nearly 90 percent of Mormons reported tithing regularly, new research shows. Researchers who presented their findings on the charitable habits of members of the Church of Jesus Church of Latter-day Saints are confident in the reliability of the responses from Mormons surveyed. Ram Cnaan, director of the Program for Religion and Social Policy Research for the University of Pennsylvania, told The Christian Post that although his research did not verify the responses from Mormons surveyed, other studies indicated that the data could be trusted.
