Since some people appear to be confused about the Roper Report, I
am enclosing a brief portion of the Introduction, taken from
"Unusual Personal Experiences: An Analysis From Three Major
Surveys Conducted by the Roper Organization."



Unusual Personal Experiences was published and copyrighted (1992)
by the Bigelow Holding Corporation.

"This summary presents the findings of research conducted for
Bigelow Holding Company by The Roper Organization.  Results
presented in this summary are the summation of a question
included in three separate waves of Roper's in-home omnibus
service, Limobus [TM].

"Roper's Limobus [TM] service offers clients the ability to
"tack-on" questions to the regularly scheduled in-home service,
Roper Reports-.  A limited number of omnibus questions are
available each month in Roper Reports [TM].  Every effort is made
to place questions, within the preset questionnaire, in such a
way as to eliminate question order bias and allow the
questionnaire to "flow" smoothly.

"The Roper Reports [TM] questionnaire is a mixture of lifestyle,
behavior, attitude, and opinion questions.  Topics as diverse as
Activities in Past Week, and Optimism/Pessimism About Our
Country's Future form the vast majority of the Roper Reports [TM]
questionnaire.

"The three separate waves of Bigelow Holding Company's Limobus
[TM] questionnaire were conducted in July, August, and September
of 1991.  Sample sizes in each wave were, respectively, 1,992,
1,983, and 1,972, resulting in a total of 5,947 respondents.

"The technical appendix of this summary presents the methodology
employed by The Roper Organization to produce a sample of
respondents representative of the population of the continental
United States.

"While individual month readings for the question asked have a
margin of sampling error of =B1 3%, the averaged total sample
presented in this summary carries a =B1 1.4% margin of sampling
error."

Of course, Dennis has already stated that the Roper Poll was
conducted in person but now Bob Shell has confused matters some.
Hope this helps straighten things out.
