The October 2004 "Lancet" study done by public health experts from Johns Hopkins University and published on October 29, 2004, in "The Lancet" medical journal, estimated that 100,000 "excess" Iraqi deaths from all causes had occurred since the U.S. invasion began.
The study did not attempt to measure how many of these were civilian, but the study's authors have said they believe that the "vast majority" were non-combatants, based on 7% of the casualties being women and 46% being children under the age of 15 (including Falluja data).
To arrive at these excess death figures, a survey was taken from 988 Iraqi households in 33 clusters throughout Iraq, in which the residents were asked how many people lived there and how many births and deaths there had been since the war began.
They then compared the death rate with the average from the 15 months before the war.
Iraqis were found to be 1.5 times more likely to die from all causes after the invasion (rising from 0.5% to 0.79% per year) than in the 15 months preceding the war, producing an estimate of 98,000 excess deaths.
This figure excluded data from one cluster in Falluja, which was deemed too much of an outlier for inclusion in the national estimate.
If it included data from Falluja, which showed a higher rate of violent deaths than the other 32 clusters combined, the increased death rate would be raised from 1.5 to 2.5 fold, violent deaths would be 58 times more likely with most of them due to air-strikes by coalition forces, and an additional 200,000 fatalities would be estimated.
The study contains the following Summary: Background: In March 2003, military forces, mainly from the USA and the UK, invaded Iraq.
We did a survey to compare mortality during the period of 14.6 months before the invasion with the 17.8 months after it.
Methods: A cluster sample survey was undertaken throughout Iraq during September 2004.
33 clusters of 30 households each were interviewed about household composition, births, and deaths since January 2002.
In those households reporting deaths, the date, cause, and circumstances of violent deaths were recorded.
We assessed the relative risk of death associated with the 2003 invasion and occupation by comparing mortality in the 17.8 months after the invasion with the 14.6-month period preceding it.
Findings: The risk of death was estimated to be 2.5-fold (95% CI 1.6–4.2) higher after the invasion when compared with the preinvasion period.
Two-thirds of all violent deaths were reported in one cluster in the city of Falluja.
If we exclude the Falluja data, the risk of death is 1.5-fold (1.1–2.3) higher after the invasion.
We estimate that 98,000 more deaths than expected (8000-194,000) happened after the invasion outside of Falluja and far more if the outlier Falluja cluster is included.
The major causes of death before the invasion were myocardial infarction, cerebrovascular accidents, and other chronic disorders whereas after the invasion violence was the primary cause of death.
Violent deaths were widespread, reported in 15 of 33 clusters, and were mainly attributed to coalition forces.
Most individuals reportedly killed by coalition forces were men.
The risk of death from violence in the period after the invasion was 58 times higher (95% CI 8.1–419) than in the period before the war.
Interpretation: Making conservative assumptions, we think that about 100,000 excess deaths, or more have happened since the 2003 invasion of Iraq.
Violence accounted for most of the excess deaths and air strikes from coalition forces accounted for most violent deaths.
We have shown that collection of public-health information is possible even during periods of extreme violence.
Our results need further verification and should lead to changes to reduce noncombatant deaths from air strikes.

When World War II was declared in 1939, it had a negative effect on association football; competitions were suspended and players signed up to fight, resulting in the deaths of many players. 
The Sisterhood Method is the commonest household survey for estimating maternal deaths.
It is quick, cheap, and reduces sample size requirements; in countries or areas with high levels of maternal deaths, i.e.
over 500 maternal deaths per 100,000 live births, a sample size of only 4000 households or less is acceptable for this method.
But the method still provides a useful means of assessing maternal mortality.
This method includes only 4 simple questions about the sisters of the woman in question:Question 1: How many sisters have you ever had, born to the same mother, who ever reached the age 15 (or who were ever married), including those who are now dead?Question 2: How many of your sisters who reached the age of 15 are alive now?Question 3: How many of these sisters are dead?Question 4: How many of your sisters who are dead died during a pregnancy or during childbirth, or during the six weeks after the end of a pregnancy? 
The Black Hawk War resulted in the deaths of 77 white settlers, militiamen, and regular soldiers.
This figure does not included the deaths from cholera suffered by the relief force under General Winfield Scott.
Estimates of how many members of the British Band died during the conflict range from about 450 to 600, or about half of the 1,100 people who entered Illinois with Black Hawk in 1832.
A number of American men with political ambitions fought in the Black Hawk War.
At least seven future U.S.
Senators took part, as did four future Illinois governors, as well as future governors of Michigan, Nebraska, and the Wisconsin Territory.
The Black Hawk War demonstrated to American officials the need for mounted troops to fight a mounted foe.
During the war, the U.S. Army did not have cavalry; the only mounted soldiers were part-time volunteers.
After the war, Congress created the Mounted Ranger Battalion under the command of Henry Dodge, which was expanded to the 1st Cavalry Regiment in 1833. 
Kavanagh honours former students who died in war.
Many former Christian Brothers students died on war service during the first world war.
For example, there were at least 83 war deaths from an average school attendance in 1893-1895 of 256 boys meaning that 32.42 percent of boys enrolled at that time died overseas in action.49 ex-students of the Christian Brothers died in the second world war.
