I still had my library copy of Titanic: Voices from the Disaster on hand, so I went back and examined the charts in the back. And I think you’re (at least partly) wrong.
I agree that the charts are badly labeled, and therein, I think, lies the problem. But I got out my calculator, and all the numbers add up: it just isn’t always clear what numbers you’re looking at. Which, I agree, is a problem in and of itself.
First of all, these charts include only passengers, not crew, so the total numbers seem a bit low, but they’re not.
The first chart is for third-class passengers only. The columns list men, women and children saved and men, women, and children lost. The rows indicate the number of British, non-British, and those who boarded at Cherbourg and at Queenstown. The totals add up to 181 third-class passengers saved and 528 lost, out of a total of 709 third-class passengers.
This is followed by some text about the number of children/infants on board, and the statement that “Overall there were a total of 1,317 passengers on board. First class 324; Second class 284 (including 8 band members); Third class 709.”
Then there is a statement that “Of those 524 were women and children.” Which apparently means “of those 1317 passengers, 524 were women and children.” Then follows a chart showing what happened to the women and children: the columns are the classes, and the rows are “saved” and “lost.” So, out of 148 first-class women and children, 143 were saved (or 96.6%) and 5 were lost. In second class, 105 out of 117 women and children were saved, or 89.7%. In third class, 121 out of 259 women and children were saved, or 46.7%. The percentages (which I checked), are given in the text below the chart. And the totals are right: 148+117+259=524.
The third chart is for men, and again has them listed by class (columns) and saved/lost (rows). So 58 out of 176 first-class men (33%) were saved; 118 were lost. In second class, 13 out of 167 (7.8%) were saved and 154 were lost. In third class, 60 out of 450 (13.3%) were saved and 390 were lost.
Then there’s some more text that tells us that 369 women and children and 131 men were saved, for a total of 500, or 38% of passengers. And that’s all there in the charts: 143+105+121+58+13+60=500.
I think the lesson here is that when making charts to show data, especially in a book that is aimed at people who don’t have a lot of experience in reading charts, it is important to label and explain them carefully. At the top of the page, she notes: “Created by Lester Mitcham and used with permission.” I just went and looked up the citation Hopkinson lists on this page and discovered that she pretty much just took everything straight from the website, and he doesn’t have things labeled very well, either. I think in her situation, I would have redone the charts to make them more clear, then cited Mitcham as the data’s source.
Finally, two things: First, sorry for mixing up your having not read the Lord book with your not having seen the movie. Of course you’ve seen the movie, and I should have remembered! And second, I really like your conspiracy theory with the zombies!
