Statistical Analysis Raises Civil War Death Count By 20%

Hugh Pickens writes "For more than a century, it has been accepted that about 620,000 Americans died in the the bloodiest, most devastating conflict in American history. But now, BBC reports that historian J. David Hacker has used sophisticated statistical software to determine the war's death toll and found that civil war dead may have been undercounted by as many as 130,000. Hacker began by taking digitized samples from the decennial census counts taken from 1850-1880. Using statistical package SPSS, Hacker counted the number of native-born white men of military age in 1860 and determined how many of that group were still alive in 1870 and compared that survival rate with the survival rates of the men of the same ages from 1850-1860, and from 1870-1880 — the 10-year census periods before and after the Civil War. The calculations yielded the number of 'excess' deaths of military-age men between 1860-1870 — the number who died in the war or in the five subsequent years from causes related to the war. Hacker's findings, published in the December 2011 issue of Civil War History, have been endorsed by some of the leading historians of the conflict. 'The difference between the two estimates is large enough to change the way we look at the war,' writes Hacker. 'The war touched more lives and communities more deeply than we thought, and thus shaped the course of the ensuing decades of American history in ways we have not yet fully grasped. True, the war was terrible in either case. But just how terrible, and just how extensive its consequences, can only be known when we have a better count of the Civil War dead.'"

  1. And so history becomes a science by Kupfernigk · · Score: 5, Interesting
    History seems to be benefiting from a new generation of numerate historians. It was an earlier computer analysis of the accounts of the British Royal Navy that showed that for many years it was the most expensive arm of government, and how important its financing was as a cause of the English Civil Wars. (I'm sure there's a lot more like this going on but this happens to be my period of interest.)

    I'd like to see the same analysis applied to WW2 and Vietnam, especially the excess fatalities for 5 years after the wars. I am pretty sure the real costs of wars are systematically concealed by governments.

      I actually dislike this kind of numeric analysis. I don't think it is appropriate for history. So there are 'missing people' from the 1860s...those missing people could easily have gone to Canada or Mexico. They could have emigrated to Europe. They could have headed out West and been out of touch with US authorities for years at a time, missing censuses and the like. They certainly had motivation to flee...there was a huge war with drafts on both sides going on, why not head out?

      This study is certainly using census data, with all of its warts and flaws.

  2. Count still too low? by Nidi62 · · Score: 5, Interesting
    Looking at only native-born white men of military age still really underestimates the participation and casualty levels, unless they are doing a lot of extrapolation. Remember, you had boys as young as 12 or 13 volunteering, and while they were in most cases drummers, that could still put them in the thick of the fighting, and many would have lied about their age to follow their fathers or brothers. There were women that fought as men (only a few cases are known, but there were probably more). Many immigrants were likely pressed into service as soon as they got off the boats, and a lot of them were probably not documented accurately. And lastly (and the most un-PC) there were the free blacks that fought on both sides. While most blacks fought for the North, there was a not insignificant number of free blacks that fought for the South. Of course it goes against the commonly taught narrative that the Civil War was about slavery and not a conflict between differing economic systems and beliefs in government, so this last bit is rarely mentioned, which gives a grave disservice to all those that fought. In any case, there were many demographics beyond what this latest study measured that fought in the war, and a lot of them are probably unmeasurable, so we will never know exactly how many fought and how many died, but I suspect that even this latest number is on the low side.

    And for the record yes, I have a history degree (for which I wrote a major paper on the historiography of the Civil War) and have even worked in a Civil War museum, so I know what I'm talking about.

    Yeah, that's one of the arguments I've found particularly odd, because it's not like others are putting words in the Confederates' mouths. The states each wrote declarations explaining why they seceded, which we can read to gain some insight into their stated reasons for leaving the union.

    For example, in the "Declaration of the Immediate Causes Which Induce and Justify the Secession of South Carolina from the Federal Union", South Carolina's government makes it clear that their secession is pretty much entirely motivated by a desire to protect slavery from possibly being abolished.

    Like eliminating slavery.

    only if you are naive and believe such a simplistic bullshit. WMD in Iraq anyone? Omg nukes in Iran? Terrorists and pedophiles coming for your first born? It's all propaganda.
    Slavery was already on its way out, because slaves have low productivity and trained and motivated workers provided more profits despite wage cost.

    I guess it's easy for average Murrican to dismiss criticism of the Civil War as a fringe talk after decades of brainwashing and all those profits reaped thanks to the position of global hegemony. Everybody likes to be the best and the forced unity made that possible.
    Look at former Soviet union. Bitchslapped baltic states and crushed internal opposition, victor in WW2 and top2 position from then on for few decades to come. It was a horrible country yet many citizens have the nostalgia for the global superpower times. I guess for your average peon it was well worth it to sacrifice millions for greater good. FFF that.

    The progress in social matters is slowed down when the political game is played at the top levels. If social issues were handled more locally (eg at the state level) the progressive regions would be long done with gay marriages with child adoption, marijuana and shit, and at the same time people in Backwardsville would be able to enjoy their closemindedness. Yes, it would suck for people with 'problems' born in the wrong part of the country, but with 50 states you would have an option to move to likeminded area.
    One-size-fits-all solutions forced by the government require every interest group from every corner of the country to weigh in in order not to lose and that leads to gridlock, wartime rhetoric and deep divides across the society. That slows down the progress and makes people feel opressed by 'them' whoever that might be.

    Good lord, I see we have a Lost Cause adherent here. Try reading the records from the seccession conventions of any of the Southern states. How about Alexander Stevens' Cornerstone Speech? State's rights was a myth made up by ex-Confederates AFTER the war was over. Men like Jubal Early, P.G.T. Beauregard, Alexander Stevens and Jefferson Davis made it their duty after the war to totally obscure slavery's role what the confederacy stood for. Literally, hundreds of historians have destroyed the foolish notion of the war for state's rights. http://www.amazon.com/What-This-Cruel-War-Over/dp/0307277321/ref=sr_1_1?s=books&ie=UTF8&qid=1334149324&sr=1-1 http://www.amazon.com/Race-Reunion-Civil-American-Memory/dp/0674008197/ref=sr_1_1?s=books&ie=UTF8&qid=1334149363&sr=1-1 http://www.amazon.com/Causes-Won-Lost-Forgotten-Hollywood/dp/0807832065/ref=sr_1_1?s=books&ie=UTF8&qid=1334149385&sr=1-1 http://www.amazon.com/Myth-Lost-Cause-Civil-History/dp/0253222664/ref=pd_sim_b_1 Any of these books will enlighten you.

  8. Numerical analysis not appropriate? by Kupfernigk · · Score: 4, Insightful

    Well, you are entitled to your opinion. But as the analysis did its best to allow for immigration and emigration, and did comparisons with other periods, your argument needs a bit more beef than "dislike". In my own field of interest, naval history, things like manning levels, pay rates, construction, weights of shot, water capacity, access to navigational equipment and the like turn out to be far better predictors of outcomes than the "Great Man" ideas of historians of the past. The outcome of the Battle of Britain was almost entirely determined by engineering factors - radar, and the fact that the British fighters were developed a little later than the German ones and so benefited from better engineering. The massacres in Rwanda and El Salvador can be better understood by analysing population density, land use and economic power than by speculation over tribal or political conflict. Proper statistical analysis of history - not numeric analysis, whatever that is - is not only illuminating in itself but could eventually give models with predictive power.

      Yes, it appears that the study did a reasonable job, and its findings jibe with the opinions of many historians that deaths were undercounted.

      At the same time, a one-off historical event is not quite the same as a physics experiment, or chemistry, or even psychology. Exactly what other time period or event could you compare the Civil War to in order to estimate war-time emigration/immigration rates? Doesn't seem like you can control very well for that. Considering the enormity of 600,000 dying, the scorched-earth tactics of the Union, draft riots, etc, I doubt that there really is a comparable, well-documented period to be found.

      Also, I can't find the actual article, but the press didn't report any error margins, which might in fact be huge. (Not even sure how accurate those estimates would be.) If you know anything about statistics, a number with no error margins (confidence intervals, whatever you call them) is meaningless.

      The fact that the press talks about a "sophisticated statistics package" is a red flag, but it may be due to reporters and not the actual study. (You can easily obtain, for free, a statistical package that can do whatever calculations they did. It's not the package that matters, it's the skill of the analyst.)

      Yes, statistics and modeling can be useful in any field. But your unbridled enthusiasm isn't warranted. As you point out, in the past historians have had pet theories that were essentially Appeals to Authority (i.e. "I'm a famous historian and this is what I think"), but you have to be careful of the other side of the Appeal to Authority coin: "I used a sophisticated statistics tool to prove ...".
