How the Gaza Ministry of Health Fakes Casualty Numbers
The evidence is in their own poorly fabricated figures
March 06, 2024
The
number of civilian casualties in Gaza has been at the center of
international attention since the start of the war. The main source for
the data has been the Hamas-controlled Gaza Health Ministry, which now
claims more than 30,000 dead, the majority of which it says are children
and women. Recently, the Biden administration lent legitimacy to Hamas’
figure. When asked at a House Armed Services Committee hearing last
week how many Palestinian women and children have been killed since Oct.
7, Secretary of Defense Lloyd Austin said the number was “over 25,000.”
The Pentagon quickly clarified that the secretary “was citing an
estimate from the Hamas-controlled Health Ministry.” President Biden
himself had earlier cited this figure, asserting that “too many, too
many of the over 27,000 Palestinians killed in this conflict have been
innocent civilians and children, including thousands of children.” The
White House also explained that the president “was referring to publicly
available data about the total number of casualties.”
Here’s
the problem with this data: The numbers are not real. That much is
obvious to anyone who understands how naturally occurring numbers work.
The casualties are not overwhelmingly women and children, and the
majority may be Hamas fighters.
If Hamas’ numbers are faked or fraudulent in some way, there may be evidence in the numbers themselves
that can demonstrate it. While there is not much data available, there
is a little, and it is enough: From Oct. 26 until Nov. 10, 2023, the
Gaza Health Ministry released daily casualty figures that include both a
total number and a specific number of women and children.
The
first place to look is the reported “total” number of deaths. The graph
of total deaths by date is increasing with almost metronomical
linearity, as the graph in Figure 1 reveals.b v
The
graph reveals an extremely regular increase in casualties over the
period. Data aggregated by the author and provided by the United Nations
Office for the Coordination of Humanitarian Affairs (OCHA), based on
Gaza MoH figures.
This
regularity is almost surely not real. One would expect quite a bit of
variation day to day. In fact, the daily reported casualty count over
this period averages 270 plus or minus about 15%. This is strikingly
little variation. There should be days with twice the average or more
and others with half or less. Perhaps what is happening is the Gaza
ministry is releasing fake daily numbers that vary too little because
they do not have a clear understanding of the behavior of naturally
occurring numbers. Unfortunately, verified control data is not available
to formally test this conclusion, but the details of the daily counts
render the numbers suspicious.
Similarly,
we should see variation in the number of child casualties that tracks
the variation in the number of women. This is because the daily
variation in death counts is caused by the variation in the number of
strikes on residential buildings and tunnels which should result in
considerable variability in the totals but less variation in the
percentage of deaths across groups. This is a basic statistical fact
about chance variability. Consequently, on the days with many women
casualties there should be large numbers of children casualties, and on
the days when just a few women are reported to have been killed, just a
few children should be reported. This relationship can be measured and
quantified by the R-square (R2 ) statistic that measures how correlated
the daily casualty count for women is with the daily casualty count for
children. If the numbers were real, we would expect R2 to be
substantively larger than 0, tending closer to 1.0. But R2 is .017 which
is statistically and substantively not different from 0.
The
daily number of children reported to have been killed is totally
unrelated to the number of women reported. The R2 is .017 and the
relationship is statistically and substantively insignificant.
This
lack of correlation is the second circumstantial piece of evidence
suggesting the numbers are not real. But there is more. The daily number
of women casualties should be highly correlated with the number of
non-women and non-children (i.e., men) reported. Again, this is expected
because of the nature of battle. The ebbs and flows of the bombings and
attacks by Israel should cause the daily count to move together. But
that is not what the data show. Not only is there not a positive
correlation, there is a strong negative correlation, which makes no
sense at all and establishes the third piece of evidence that the
numbers are not real.
The correlation between the daily men and daily women death count is absurdly strong and negative (p-value < .0001).
Consider
some further anomalies in the data: First, the death count reported on
Oct. 29 contradicts the numbers reported on the 28th, insofar as they
imply that 26 men came back to life. This can happen because of
misattribution or just reporting error. There are a few other days where
the numbers of men are reported to be near 0. If these were just
reporting errors, then on those days where the death count for men
appears to be in error, the women’s count should be typical, at least on
average. But it turns out that on the three days when the men’s count
is near zero, suggesting an error, the women’s count is high. In fact,
the three highest daily women casualty count occurs on those three days.
There
are three days where the male casualty count is close to 0. These three
days correspond to the three highest daily women’s casualty count.
Taken
together, what does this all imply? While the evidence is not
dispositive, it is highly suggestive that a process unconnected or
loosely connected to reality was used to report the numbers. Most
likely, the Hamas ministry settled on a daily total arbitrarily. We know
this because the daily totals increase too consistently to be real.
Then they assigned about 70% of the total to be women and children,
splitting that amount randomly from day to day. Then they in-filled the
number of men as set by the predetermined total. This explains all the
data observed.
There
are other obvious red flags. The Gaza Health Ministry has consistently
claimed that about 70% of the casualties are women or children. This
total is far higher than the numbers reported in earlier conflicts with
Israel. Another red flag, raised by Salo Aizenberg and written
about extensively, is that if 70% of the casualties are women and
children and 25% of the population is adult male, then either Israel is
not successfully eliminating Hamas fighters or adult male casualty
counts are extremely low. This by itself strongly suggests that the
numbers are at a minimum grossly inaccurate and quite probably outright
faked. Finally, on Feb. 15, Hamas admitted to losing 6,000 of its
fighters, which represents more than 20% of the total number of
casualties reported.
Taken
together, Hamas is reporting not only that 70% of casualties are women
and children but also that 20% are fighters. This is not possible unless
Israel is somehow not killing noncombatant men, or else Hamas is
claiming that almost all the men in Gaza are Hamas fighters.
Are
there better numbers? Some objective commentators have acknowledged
Hamas’ numbers in previous battles with Israel to be roughly accurate.
Nevertheless, this war is wholly unlike its predecessors in scale or
scope; international observers who were able to monitor previous wars
are now completely absent, so the past can’t be assumed to be a reliable
guide. The fog of war is especially thick in Gaza, making it impossible
to quickly determine civilian death totals with any accuracy. Not only
do official Palestinian death counts fail to differentiate soldiers from
children, but Hamas also blames all deaths on Israel even if caused by
Hamas’ own misfired rockets,
accidental explosions, deliberate killings, or internal battles. One
group of researchers at the Johns Hopkins Bloomberg School of Public
Health compared Hamas reports to data on UNRWA workers. They argued
that because the death rates were approximately similar, Hamas’ numbers
must not be inflated. But their argument relied on a crucial and
unverified assumption: that UNRWA workers are not disproportionately
more likely to be killed than the general population. That premise
exploded when it was uncovered that a sizable fraction of UNRWA workers are affiliated with Hamas. Some were even exposed as having participated in the Oct. 7 massacre itself.
The
truth can’t yet be known and probably never will be. The total civilian
casualty count is likely to be extremely overstated. Israel estimates
that at least 12,000 fighters have been killed. If that number proves to
be even reasonably accurate, then the ratio of noncombatant casualties
to combatants is remarkably low: at most 1.4 to 1 and perhaps as low as 1
to 1. By historical standards
of urban warfare, where combatants are embedded above and below into
civilian population centers, this is a remarkable and successful effort
to prevent unnecessary loss of life while fighting an implacable enemy
that protects itself with civilians.
