As a research cohort by age, gender, name this would be fascinating. My bias would be: weights highly to middle age and older males with traditional biblical names, and women tend to be MUCH more traditional biblical names but younger.
That would be somewhat interesting, but it's tempered by relationship: the fine article mentions only that the demographics are "affiliated" with Moody. This could range from vendors & suppliers to mailing lists to groups of folks in neighborhoods targeted for evangelizing (should they even have such a program). It doesn't say which side of the affiliation initiated the relationship.
