| \details{ |
| The sinking of the Titanic is a famous event, and new books are still |
| being published about it. Many well-known facts---from the |
| proportions of first-class passengers to the \sQuote{women and |
| children first} policy, and the fact that that policy was not |
| entirely successful in saving the women and children in the third |
| class---are reflected in the survival rates for various classes of |
| passenger. |
| |
| These data were originally collected by the British Board of Trade in |
| their investigation of the sinking. Note that there is not complete |
| agreement among primary sources as to the exact numbers on board, |
| rescued, or lost. |
| |
| Due in particular to the very successful film \sQuote{Titanic}, the last |
| years saw a rise in public interest in the Titanic. Very detailed |
| data about the passengers is now available on the Internet, at sites |
| such as \emph{Encyclopedia Titanica} |
| (\url{https://www.encyclopedia-titanica.org/}). |
