Statistical Summary of Near-Death
Experience Reports
Based upon reports from the International
Association
for Near-Death Studies (IANDS)
By Vince Migliore
May, 2007
I.
Executive Summary
A. Summary
A sample of 787 near-death
experience (NDE) reports collected by the International Association for
Near-Death Studies (IANDS)
are summarized in this document. Accounts date from the 1960s to 2001. The
sample is not representative of the US population, as it was
collected over the Internet, by mail, and by verbal reports from around the
world. Respondents are more often female and in the younger
age groups than both the US and world populations. The sheer number of
cases, however, makes this a valuable resource for researchers
and investigators. The database of reports supplied by IANDS required
editing and coding in order to adapt it to statistical data processing.
This summation of survey
results lists major findings and cross-tabulations, without speculation or
attempts to formulate a theory of how
NDEs relate to human or spiritual
experiences.
Some of the more
interesting significant cross-tabulations appear below. For further details
see the cross-tab notes after each table,
and in the appendices.
-
Most NDE events are considered
wonderful, 54.0%, while 37.3% have mixed perceptions. Only 8.6% describe
their experience as frightening.
-
Sometimes, an important finding is that
there are no significant differences between groups. No differences in
near-death experiences were found for
white versus non-white
respondents. Similarly, there were very few differences between those
experiences occurring inside versus outside of the
United States.
-
The NDE contains many common elements.
Two thirds report an out-of-body experience, and almost as many see a
light. More than half report strong
emotional tone and receiving
knowledge. Almost half report seeing unearthly beings.
-
The out-of-body experience is more often
reported by those under 40 years of age. For the total sample 67.7%
report an out-of-body episode,
but this is significantly lower at 59.6%
for those aged 40 to 49, and 48.4% for those 50 and older. The highest
incidence is 76.2% in the 10 to 19
year age group. An out-of-body is
also more often associated with clinical death, 75.1% versus 63.0% for
those with a non-life threatening event.
-
Encountering unearthly beings is higher
for females, 53.1%, compared to males, 40.3%.
-
Reports of both darkness and void drop
off significantly after age 50. Darkness and void are higher for those
reporting a frightening experience.
-
A life review is least common for those
aged 50 and over. Their rate of reporting is 10.9%, about half of the
total sample, 21.6%. The life review is
also higher for those who report
clinical death.
-
Changes in feelings about death are
reported highest for those who also report a wonderful experience, 86.5%
versus 75.4% for those with a frightening
experience. It was also
highest for those who reported clinical death, 87.8% compared to 83.0%
for the whole sample.
-
The development of healing and psychic
abilities is significantly higher among women, 71.4%, compared to men,
60.7%. Such abilities occur most often
for those who report clinical
death, 75.5%, compared to 61.9% for those with a non-life threatening
experience.

II.
Sample Considerations
A. Sampling Error
The reports submitted to the
International Association for Near-Death Studies (IANDS) represent a
convenience sample, as self-selecting
respondents voluntarily submitted the
data. This creates sampling errors; those factors that render the sample
less than perfect because of the
way the data was collected. The fact that
the sample is over 700 cases, however, provides a strong possibility that
widespread representation
of near-death experience (NDE) are included in
this database. The multiple-source sample also shows a skewing by age and
gender,
compared to the known population of the US. The tables in this
section omit respondents from other countries, in order to compare the
American respondents to US Census data from the year 2000.
Your age at time of
experience:
Your gender:
The age of reporters at the
time of their experience is skewed toward younger age groups, with people
over 50 under-represented in the
sample (Table 1). Likewise, women are
over-represented in the sample (Table 2). This type of error makes it
difficult to tell, for example,
if women actually have more NDEs, or, more
likely, they simply report their experiences more often than men.

Most reports were received
from people within the US (Table 3). Europe provided the next largest group
of contributors. The survey
results presented here cannot be projected to
represent the population of the US, or the world population, but rather
simply summarize
the reports collected by IANDS up to 2001.

Age now
Most of those who
experienced an NDE reported it during middle age (Table 4). Since most of
the experiences occurred prior to age 30,
and most reporting occurs after
age 30, it appears there is a long lag between the event and the time of
reporting for this sample.

There were too
few cases of racial categories to make meaningful comparisons. Instead, all
the non-Caucasian respondents were grouped
and compared to Caucasians.
Sometimes, an important finding is that there are no significant differences
between groups. This is true for race.
No differences in near-death
experiences were found for white versus non-white respondents. Similarly,
there were few differences
between those inside versus those outside the
United States.
|
|
B. Editing, Coding, and Data
Clean-up
Data editing and recoding is
often required on a raw database when respondent information is unclear or
contradictory. For example, in the
question Your Condition During the
Experience, someone may check “Other”, then go on to describe a
drowning where they were
underwater for 15 minutes, with no vital signs.
This must be recoded from “Other” into the “Clinical Death” category. All
edits and recoding
were reviewed by three researchers in a procedure whereby
two researchers agree on the recoding, and a third reviews the procedure and
acts as a tie-breaker.
Two important variables,
Your Condition During the Experience, and Circumstances of
Your Experience, required extensive
editing and recoding, while
other variables required only minor editing. The Circumstances
question required the creation of a few new
response categories.
Respondent comments to questions, captured along with the numerical data,
were used to guide the recoding decisions.

III.
Findings and Cross-Tabulations
A. Causes and Circumstances
Q1. Your condition during the experience:
Clinical death occurred in
one fourth of the sample population, 24.8%, while serious conditions
occurred in 39.1% (Table 5). This is a
difficult question to answer due to
the lack of clinical data, which often makes it impossible to tell which
category applies. Such uncertainty
diminishes the value of the results. It
is interesting that approximately one quarter of all respondents, 24.3%,
report the experience was
triggered by a non-life threatening situation.
Apparently, the definition of “near-death experience” must be examined and
clearly defined
for respondents.

Significant Cross-tab
Findings:
-
Male respondents report clinical death
more often than female respondents, 28.7% versus 21.8% respectively.
-
Those who indicate poor health at the
time of their experience report clinical death more often. Likewise,
non-life threatening NDEs are more
often reported by those in good to
excellent health 31.1% versus 12.8% for those in poor to fair health.
Q2. Circumstances of the
experience:
As with Q1, this topic poses
difficulties, as often there are multiple, overlapping triggers to the NDE
experience (Table 6). Accidents
and illnesses are the most common causes.

Significant Cross-tab Findings:
-
Accidents are reported more often by
those under 10 years of age, and among males. Accidents account for
27.8% of all NDEs, but that is much
higher for children under 10, at
45.1%.
-
Illness is reported more often by
females, 15.9% as opposed to 10.8% for males.
-
Heart attacks are reported more often by
men, and those 40 years of age or older. Men report a 9.8% incidence
compared to 2.8% for women.
Heart attacks constitute 5.9% of the total
causes of NDEs, but among those who indicate clinical death, heart
attacks account for 14.5% of cases.
Q3. Your status of health after the experience:Respondents were asked to
rate their health at the time of their NDE experience, and now (at the time
of reporting), both using a 4-point
scale (Tables 7 and 8). Those who report
good or excellent health rose from 68.7% of respondents at the time of their NDE, to 81.4% at
the time of reporting. Health factors inherently play a
role in precipitating the experience.

Significant Cross-tab Findings:

Respondents under 30 report excellent
health more frequently. Those under the age of 10 at the time of their
experience report being in excellent
health 47.1% of the time, 51.6% for
those 10 to 19, and 43.5% for those in their 20s.
-
Those who report excellent health are
more likely to report a wonderful NDE and also tend to be more liberal
religiously. Excellent health is reported
by 37.8% of all respondents
but this jumps to 44.2% for those with a wonderful experience, and 44.7%
among religious liberals. Indeed, those who
report their NDE was
generated by a non-life threatening event have a relatively high
incidence of excellent health, at 49.1%, when compared to
34.0% for
those who report clinical death.
Q4. Your status of
health now:
Current health status, which
was given at the time of reporting the event, was higher than at the time of
the NDE experience. There is often
a long lag between the time of the
experience and the reporting of the event.

who are religious liberals (43.8%), and with
those who reported
excellent health at the time of their NDE (42.2%).

B. Perceptions and
Effects
Q5. At the time, did you consider the contents of your
experience: Wonderful, Frightening, Mixed
Respondents were asked how
they perceived their NDE events: as wonderful, frightening, or mixed. The
majority viewed the NDE as
wonderful, and only 8.6% as frightening, Table 9.

Significant Cross-tab Findings:
-
Those who report a wonderful experience
are more often female at 57.8% versus 47.8% for males. A wonderful
experience is described more often in
the over 40 age groups; 62.0% for
those in their 40s, and 64.1% for those 50 and over.
-
Those who report a wonderful experience
are highly correlated with the similar question of whether they view the
after-effects of their experience as
positive or disturbing.
Q6. Did your
experience include (check all that apply):
Respondents were shown a
series of check boxes and asked to indicate which elements were present in
their NDE (Table 10). The vast
majority of respondents report a multitude of
experiences associated with their NDE. Two thirds report an out-of-body
experience, and
almost as many see a light. More than half report strong
emotional tone and receiving knowledge. Almost half of the respondents
report
seeing unearthly beings.

There are 13 items that may
be checked on this experience list. Overall, respondents selected an average
of five items (4.98), with the
highest number of selections in the 30 to 39
age group (average 5.35 items each). A higher than normal number of items
were also selected
for those reporting clinical death (5.30 items each).
Significant Cross-tab Findings:
-
Sometimes the lack of significant
differences is an important finding. There are generally few differences
found in these categories by gender or race,
or whether reports come
from the US or other countries.
-
The out-of-body experience is more often
reported by those under 40 years of age. For the total sample 67.7%
report an out-of-body episode but this
is significantly lower at 59.6%
for those aged 40 to 49, and 48.4% for those 50 and older. The highest
incidence is 76.2% in the 10 to 19 year age group.
An out-of-body
experience is also more often associated with clinical death, 75.1%
versus 63.0% for those with a non-life threatening event.
-
Report of light is higher among females
(67.2%) than for males (59.7%). Light is more often associated with a
wonderful experience, 73.4%.
-
Strong emotional tone is also higher for
those reporting a wonderful experience, 68.1% compared to 54.2% who
report a mixed experience. Those
who report a frightening experience
also report a strong emotional tone, 57.7%.
-
Knowledge is reported highest in the
under age 10 group at 59.2% as opposed to 45.9% for those in their 40s,
and 40.6% for those 50 and over.
The imparting of knowledge is also
higher for those reporting a wonderful experience, 58.7%, compared to
those with a mixed experience, 48.3%,
and those with a frightening
experience, 36.4%.
-
Encountering unearthly beings is higher
for females, 53.1%, compared to males, 40.3%.
-
Reports of both darkness and void drop
off significantly after age 50. Darkness and void are higher for those
reporting a frightening experience.
Darkness is at 56.1% for those
reporting a frightening experience, compared to 28.3% for those
reporting a wonderful experience. For void, the
corresponding
percentages are 39.4% and 19.3% respectively.
-
Among all respondents, 28.5% report
experiences out of keeping with their belief systems, but this is
significantly higher for religious liberals, 35.9%.
-
The oldest age group, 50 and over, more
often sees a landscape or city, 37.5% compared to 26.2% for the entire
population.
-
Seeing deceased persons is highest in
the 30 to 39 year group, 36.8%.
-
A boundary is seen most by those in fair
to poor health, 29.6%, compared to 21.6% for those in good to excellent
health. Those who report a wonderful
experience see a boundary 25.8% of
the time, compared to 15.2% for those who report a frightening
experience.
-
A life review is least common for those
aged 50 and over. They report a life review at 10.9%, about half the
21.6% reported by the entire sample. The
life review is also higher for
those who report clinical death.
-
A vision of the future occurs mostly for
those under 40 years of age. Those 40 and over report such visions at
about half the rate of those under 40.
Q7. Have you experienced changes in any of the following resulting
from the experience?
The vast majority of
respondents had changed feelings about death after their NDE. Most
respondents reported multiple changes, averaging
4.9 items out of 8 possible
choices. The biggest change was in their feelings about death, followed by
life purpose, their belief system, and
an increase in psychic abilities
(Table 11). It’s apparent that most NDE experiences precipitate multiple
changes in perceptions and behaviors.
Age and gender seem to be a big
factors in such changes, as the highest rates of reported change tend to be
women, and people in their 30s
and 40s.

-
Changes in feelings about death are
reported highest for those who also report a wonderful experience, 86.5%
versus 75.4% for those with a
frightening experience. It was also
highest for those who reported clinical death, 87.8% compared to 83.0%
for the whole sample.
-
A sense of life purpose is relatively
consistent across all subgroups. It is highest among those who also
report positive NDE after-effects.
-
Change in belief systems is highest in
the middle age groups. Some 69.2% of all respondents report belief
changes, but this is highest in the 20 to 29
age group (74.6%), and
lowest in the 50 and over group (54.8%). It is also relatively high
among those who describe their experience as wonderful,
72.7%, versus
55.4% for those with a frightening experience.
-
The development of healing and psychic
abilities is significantly higher among women, 71.4%, compared to men,
60.7%. Such abilities occur most
often for those who report clinical
death, 75.5%, compared to 61.9% for those with a non-life threatening
experience.
-
Feelings about friends and society show
the biggest change for those respondents in the 30 to 39 age group,
72.3%. This change is also high for
those who report clinical death,
69.8%.
-
Changes in job or studies is lowest for
those who report a non-life threatening experience, 38.3%, compared to
52.9% for those who report clinical
death, and 48.8% who report a
serious condition.
-
Physical after-effects occur more among
women, 37.4%, than among men, 30.0%. They are also more common among
those who report poor to fair
health at the time, 38.3%, compared to
28.8% for those in good or excellent health.
Q8. Have these changes been: Positive, Mixed, Disturbing
Less than 3% of respondents
found after-effects of the experience disturbing; one third report mixed
feelings but the majority report a positive perception of after-effects
(Table 12).

-
The highest positive ratings are given
by those 50 years of age or older, 68.8%.
Q9. Has your life
changed specifically as a result of your experience?
Only a small number of
people, 17%, report no life change as a result of their experience (Table
13).

Q10. Over time, did
your after-effect: Increase, Decrease, Stay the Same
Almost half of respondents
(47.6%) report the effects of the NDE increased over time (Table 14). Only
14% report the changed decreased

Q13b. Your religious
background: Conservative, Moderate, Liberal
Most respondents consider
themselves religious liberals. Religious liberals more often describe their
NDE experience as wonderful. It is
unknown whether or not the experience
made them more liberal, or if being liberal affected the NDE experience.

Q15. Your race:
Most respondents report
their race as White (Table 17). Minorities are under-represented in these
reports. The total sample includes too
few cases in minority categories to
break out results by ethnic group. Instead, cross-tabulations are by White
and Non-White only.

Q16. Your country of
birth:
Q17. Country of family
origin
Both of these questions
contained too many inconsistencies and contradictions to provide reliable
results and therefore are not included
in this report.
