Survivor count

The number of surviving Colonial citizens and military in the fleet was provided at intervals throughout the first season on a whiteboard on Colonial One, and in one instance spoken aloud in dialogue. In the second season, this number appears in the opening credits of every episode (sometimes jokingly referred to as the "Countdown to Extinction"), and displays limited omniscience, updating itself to reflect the deaths on Kobol early in that season. This page collects the figures available thus far, cross-referenced with date information from Re-Imagined Series Timeline.

Analysis

• The loss of the Olympic Carrier was catastrophic compared to any subsequent events to befall the fleet. Clearly no ship has been lost off-screen since that episode, and if any ship is destroyed, it will be quite noticeable. The total fleet count remains as it was at the start of the series (about 40 ships according to the Mini-Series, about 75 according to "The Farm").

• Since the end of "33", the fleet's population has been dying off at a fairly steady rate of approximately 2.1 persons per day. At this rate, the fleet will be completely depopulated in 62 years. If the show's failure to supply concrete dates continues during the remainder of the second season, perhaps the "half-life" of the fleet's population can be used to "carbon date" future episodes.
