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 in Season Five. 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.
Villain: Banished to the Phantom Zone (Nam-Ek, Aethyr)
The Disciples of Zod kill perhaps a dozen police officers. They almost choke Lois before Lana distracts them. Clark saves Chloe from hypothermia by taking her to the hospital and Lana when he banishes them to the Phantom Zone.
Lives saved: 45,001 (entire population of Smallville)
Villain: Deceased (Gabriel)
Gabriel Duncan shoots two guards then Clark, and when he and Chloe struggle with the gun, he inadvertedly shoots himself. However, Clark is resurrected by Jor-El and disables the missile Gabriel launched in order to save the entire town.
Buffy and the Tri-Psis kill the unfortunate pizza man, then Lana vaporizes Buffy with heat vision borrowed from Clark. Fine kills the guardian of the Vessel. Clark saves himself from being killed by Lana. With Lex's help, Clark is able to cure Chloe and Lana, and the remaining Tri-Psis of the rabies strain.
Clark resets the day when Lana dies in a car accident just after learning his secret. He then saves Lois after she falls off a stool, but Jor-El's prediction that Clark will lose a loved one comes true when Jonathan has a heart attack and dies in his family's arms.
Lois takes Chloe to the emergency room when she mysteriously finds her wrists bleeding. Clark breaks her out to rescue her from an uncertain fate in Belle Reve. Gretchen Winters then inhabits her and, along with Lois, is captured by her killer. She releases Chloe's body when she kills her murderer, saving his next victims, Chloe and Lois.
Maddie's foster mother is brutally stabbed to death by her father, Tyler McKnight, who kills a Child Protection Services agent, then tries to kill Martha, but Maddie successfully learns to control her powers and saves her.
Clark saves Graham Garrett from being hit by a car. Graham then kills a high-profile witness, then tries to kill Lex and Lana, but they are saved by Clark. Lois and Chloe save Clark when Graham knocks him out and buries him under dirt containing Kryptonite. Lex then shoots Graham dead.
