Survey Reveals Significant Growth in Born Again Population: In The Barna Group's latest study, in which 1003 lower-48 American adults were interviewed, the proportion of adults who can be classified as "born again Christians" based upon their beliefs was the highest ever measured in the quarter century that Barna has been tracking that measure. The new research found that 45% of all adults meet the criteria that The Barna Group uses to classify people as "born again." That number is up from 31% in 1983. The increase is largely attributable to a 16-point rise among Baby Boomers since the beginning of the 1990s. With 53% of Boomers currently meeting the born again criteria used by The Barna Group, that generation has now surpassed the percentage of born again adults within the preceding pair of generations. Slightly more than one-third of the younger generations - the Baby Busters and Mosaics - fit the criteria. Other demographic comparisons: women are 16% more likely than men to be born again; African-Americans are the ethnic group most likely to be born again (59%); Hispanics the least likely (32%). The South is 57% born again, while the West (33%) and Northeast (37%) have fewer born again Christians.
