**
How Many NDEs Occur in the United States Every Day?**

The
answer, with methodology presented below is
774
NDEs occurring daily in the United States.

The prevalence
of NDE in the adult population has been estimated by several major surveys.
**A Gallup Poll in
1992 led to an estimate that 13 million Americans had experienced a NDE. The
population of the United States in 1992 was approximately 260 million, leading
to an estimate of NDE prevalence of 13 million/260 million, or 5%. A survey in
Germany (Knoblauch H., Schmied, I. (2001). Different Kinds of Near-Death
Experience: A Report on a Survey of Near-Death Experiences in Germany. Journal
of Near-Death Studies, 20(1), 15-29.) found 4% of over 2000 people surveyed
reported having experienced a NDE. From these data, it is possible to estimate
the incidence of NDE, given certain assumptions.

Statistics are often presented using the aforementioned terms

The Gallup poll in 1992 was of U.S. adults, and found 5% had NDE: .05 = (number of those surveyed with a prior history of NDE)/(total number surveyed).

Therefore:

Assuming Gallup did his job and
randomly sampled the adult population: .05 * (total adult population) = number
of adults with a prior history of NDE in total adult population. In 1993 the
U.S.
adult population was approximately 260,000,000, therefore: .05 * 260,000,000 =
13,000,000 = total number of individuals with a prior history of NDE in the
total adult population.

The average age of those surveyed in the 1992
Gallup
Poll should have been approximately the average age of the adult population in
1993. This information may be available from some source I am not aware of. An
estimate of the average age of the adult population in 1993 may be made. Given
that 74 years old is the average U.S. live expectancy, and 18 years old is
adulthood, the average age of the adult population is probably close to (though
somewhat lower than) ((74 + 18)/2) = 46. So on the average, 46 years transpired
to yield 13,000,000 NDEs (note many had the experience as children, yet the
sampled population has all aged past childhood). The number of NDEs per day is
then: 13,000,000/(46 * 365.25) = 774 NDEs per day, given the previously
discussed assumptions. More precise data about the average age of the adult
population in 1993 would yield a more precise calculation.

I recognize this methodology has significant limitations which
include incorrectly assuming that 1) the number of adults is constant between 18
and 74, 2) overestimates the average adult age, and 3) assumes the probability
of NDE occurring is constant across all ages. In spite of these limitations,
this estimate of number of NDEs occurring per day is probably accurate within an
order of magnitude. I am not aware of any other methodology that has been used
to estimate the number of NDEs that occur in a given time period. The goal of
this article is not to definitively answer this question, but to encourage
further consideration of this interesting question.
