The roster answers questions you can ask a table: who, when, how long. These are the questions it cannot, worked out from the same data file the rest of the site is built from.

Every figure quoted in them is computed from the cast list rather than repeated from somewhere else, which is the rule the whole site runs on and the reason these say things the source article does not. Where a number is arguable, the piece says so and shows the working. If you want the underlying facts instead, they are in the sortable roster, the history of the show, the biographies of all 174 cast members, and the page of statistics and a quiz.
