The Pilot episode of Smallville describes the population as 25,001 in 1989 and 45,001 in 2001. For such a small town, they seem to have an inordinate number of deaths. This article will detail the body count of each episode. Serious injuries and other crimes will also be noted, but only actual lives lost will be tallied. Likewise, although Clark saves people from various ill fates, his rescues will only be counted if death seemed reasonably certain. Since the death of a metahuman is not always certain, continual updates are expected.
