This article lists the population estimates and all known fatalities from the The 100 TV series.
Population Numbers Edit
- Main article: Grounders
It is unknown how many Grounders are in the area. There are 12 Clans as well as an unknown amount of nomadic Grounders. Altogether, they do have the highest population count of the residents in the Tondc-Mount Weather area as witnessed by the sheer number of gathered warriors in "We Are Grounders (Part 2)", "Long Into an Abyss", "Rubicon", and "Blood Must Have Blood (Part 1)".
In "Long Into an Abyss", Lexa confirms that Clarke Griffin burned 300 of her warriors in "We Are Grounders (Part 2)". In "Human Trials", Finn Collins massacres 18 villagers in Tondc. In "Rubicon", Cage Wallace sends a missile to Tondc, killing 250 Grounders and Sky People. In "Hakeldama", Charles Pike, Bellamy Blake, Hannah Green, and the rest of Farm Station massacre 299 sleeping warriors.
After the Second Nuclear Apocalypse, the population of Grounders has been reduced to approximately 1,100.
In Season Five, Grounders and Sky People formed a united group named Wonkru, so it became harder to track causalities. So assuming that the rates of surving for both groups are equal, in "Pandora's Box" population dropped to 814 which leads to approx. 750 people. After the Battle for Eden, the numbers decreased even more with the remaining population around 300. Continuing with the rates, this gives approx. 275 Grounders to survive.
- Main article: Delinquents
Not including Bellamy Blake, there were 100 Delinquents sent to earth in "Pilot". After 7 deaths and after Raven Reyes's arrival in "Twilight's Last Gleaming", there were 95 Sky People on earth. Before the battle at the end of "We Are Grounders (Part 2)", Bellamy and Clarke state there were 18 dead and 82 alive. (The total ignores two people.)
After the battle, only 48 Delinquents were taken to Mount Weather, leaving behind Bellamy, Raven, and 6 other Delinquents. By the end of "Blood Must Have Blood (Part 2)", there are 46 Delinquents left along with Bellamy and Raven. At the end of "Perverse Instantiation (Part 2)", there are 44 remaining Delinquents along with Bellamy and Raven.
After the second season, the delinquents were no longer a separate group and therefore harder to identify. At least two delinquents died during the third season. Several die during the events of the fourth season, including Bree and Jasper Jordan who commit suicide as the death wave approaches.
By the end of fourth the season, there are only six delinquents confirmed alive: three went to the Go-Sci Ring, two surviving within the Second Dawn Bunker, and one living in Shallow Valley. Because there are only sixty confirmed deaths, the status of thirty-four delinquents remain unknown. If any of them remain alive, then they would have also survived within the underground bunker. At least four other delinquents had their names on Clarke's list, but it is unknown if they made it to the bunker and it is unknown if they survived the events of the following six years inside of the bunker. The Delinquents aboard the Ark formed a new group that they called Spacekru with Echo and Emori.
At least 2 delinquents died in the fifth season. Harper McIntyre died of her father's genetic condition aboard Eligius IV thirty years after the Damocles Event and Monty Green died sometime later of old age.
In "The Gospel of Josephine," Clarke Griffin was apparently killed after she was mind wiped by Russell Lightbourne to become Josephine Lightbourne's new host. However, it's revealed in "Memento Mori" and "Nevermind" that she survived due to having A.L.I.E.'s neural mesh from when she entered the City of Light to destroy the AI. Clarke later temporarily dies in "Matryoshka" when Gabriel Santiago stops her heart to remove the Mind Drive, but she is revived shortly thereafter by Bellamy. John Murphy also briefly dies in "Red Sun Rising" of seaweed toxin, but is revived by Cillian at the beginning of "The Children of Gabriel." By the end of Season Six, all of the surviving Delinquents remain alive, having lost no one aside from Clarke's brief believed death and her and Murphy's temporary deaths. However, Octavia's fate is left unknown after she is stabbed by Hope Diyoza and disappears into the anomaly.
Sky People Edit
- Main article: Sky People
Chancellor Jaha mentioned in "Contents Under Pressure" that there were 2237 people on The Ark but they only have enough Exodus ships for 700 to get to Earth. In "Unity Day", Diana Sydney's dropship escape costs the lives of hundreds of Arkers as well as everyone on board her dropship. It is estimated in "The Calm" that there were no more than 1,000 survivors and at least 1,500 dead as a result.
Project Exodus then took place and the Ark was brought to the ground. An estimate of how many survivors of the Ark made it to the ground in "We Are Grounders (Part 2)" is unknown since there are still several missing stations as of the Season Two finale. So far, Mecha Station, Alpha Station, and Factory Station are the only three stations with known survivors with Factory Station having only one survivor, Mel.
In "'Wanheda (Part 2)"', it is discovered that Farm Station survived the landing with no casualties, however, after four months trapped within Azgeda territory, only 63 Sky People survived from three times that many. In "Ye Who Enter Here", 49 Sky People are killed when Mount Weather's self-destruct sequence is initiated.
After the Second Nuclear Apocalypse, the population of the Sky People has been reduced to approximately 100.
In Season Five Grounders and Sky People formed a united group named Wonkru, so it became harder to track casualities. So assuming that the rates of surving for both groups are equal, in "Pandora's Box" the population dropped to 814 which leads to approx. 70 Sky People.
After the Battle for Eden, the numbers decreased even more with the remaining population around 300. Continuing with the rates this gives approx. 25 survivors.
In Season Six, the Sky People lost Marcus Kane due to his injuries from Michael Vinson. Kane was resurrected in the body of a young man named Gavin through a Mind Drive, but chose to commit suicide by floating in "What You Take With You" rather than continue to live on in another man's body. Abigail Griffin died she was mind wiped in "Adjustment Protocol" to become the host of Simone Lightbourne. Several members of Wonkru were killed in "The Blood of Sanctum" when Madi ordered them to attack the Primes. As the Wonkru members that were awake were mainly Sky People, an unknown number of Sky People were lost in the shooting.
Mountain Men Edit
- Main article: Mountain Men
Dr. Lorelei Tsing mentioned in "Long Into an Abyss" that there are 382 Mountain Men living inside of Mount Weather. In "Coup de Grâce", however, the number drops to 380 when a sniper from Mount Weather is killed by a Grounder and Sgt. Lovejoy is killed by Bellamy Blake. Emerson mentions in "Bitter Harvest" that during the final battles for Mount Weather, 381 people were killed: 182 men, 173 women, and 26 children, which means that Emerson is the only one to survive from 382 to 1.
In "Rubicon", Bellamy creates a radiation leak that causes the deaths of eleven Mountain Men (including Dr. Lorelei Tsing), and that puts the number of Mountain Men to 369. By the end of "Resurrection", two guardsmen are killed by Bellamy, one sniper is killed by Clarke Griffin, and five guardsmen are killed by the Delinquents in the mess hall, leaving only 361 Mountain Men left. In "Bodyguard of Lies", at least 6 more Mount Weather Guards are killed in the Acid Fog machine explosion, leaving the total at 355 Mount Weather residents.
Several more Mountain Men are killed during the Delinquent sweeps, the skirmishes on the ridge above the door and at the dam, and when they take another group of Sky People captive during "Blood Must Have Blood (Part 1)". After Clarke and Bellamy irradiate Level 5 in "Blood Must Have Blood (Part 2)", all of the Mountain Men die except for Cage Wallace and Carl Emerson. After Cage is killed by Lincoln, Carl Emerson remains the sole survivor of Mount Weather. However, Emerson is later on killed by Clarke in "Demons". His death marks the extinction of the Mountain Men. In the same episode, Emerson gives the number of Mountain Men killed by Clarke as 381. However, he may have simply been blaming her for all the deaths during the war, not just the people she directly killed.
Eligius Prisoners Edit
- Main article: Eligius Prisoners
Bellamy Blake mentioned in "Sleeping Giants" that there were originally 337 passengers living on Eligius IV. There were originally 300 prisoners, 25 guards, and 12 crew members. After the mutiny orchestrated by Charmaine Diyoza, the guards and crew were all killed save for Miles Shaw, reducing the number to 301. As a result of conflicts on Earth, the number dropped to approximately 100 prisoners who surrendered to Wonkru.
- Main article: Primes
The Primes were originally Mission Team Alpha, a 13 person team made up of scientists and their families who were sent from Earth via Eligius III to study and colonize Sanctum. During the first Red Sun eclipse, Russell Lightbourne went insane and attacked the other team members, killing several including his wife Simone and daughter Josephine. Over the next 25 years, Russell and Gabriel Santiago worked to find a way to bring back those they lost, eventually discovering a way using the Mind Drives and Nightblood hosts. The Primes became the rulers of Sanctum, worshipped by their followers as living gods. When a Prime died, their Mind Drive would be safeguarded until a new Nightblood host could be found for them to be resurrected in. However, Gabriel eventually abandoned the Primes out of guilt and founded the Children of Gabriel to stop them, destroying the remaining Nightblood embryos and becoming branded a demon by the remaining Primes.
When Eligius IV arrived in Season Six, most of the Lee family were killed following an attempt to take over the ship. After discovering that Clarke was a Nightblood, Russell turned Clarke into a host for his daughter Josephine, apparently mind wiping Clarke in the process and sparking a conflict with Clarke's friends. In turn, Josephine killed Kaylee Lee and prompted her mother to delete the Mind Drives of the Lee family, permanently killing them. As the conflict raged, several Primes were killed, particularly Josephine whose consciousness was destroyed by Clarke who survived due to having A.L.I.E.'s neural mesh. After being given Nightblood by Abby, Russell was able to resurrect all of the deceased Primes, including those who died in the conflict aside from the deleted Lee family and Priya and Ryker Desai. However, Simone Lightbourne, Miranda, Caleb and Jasmine Mason were floated by Clarke, sending their bodies into deep space where they couldn't be recovered and preventing them from being resurrected again. As of "The Blood of Sanctum," the only living and active Primes are Russell Lightbourne and Gabriel Santiago. However, Priya and Ryker's Mind Drives remain intact, leaving open the possibility that they could be resurrected again in the future.
Sanctum Citizens Edit
- Main article: Sanctum Citizens
Sanctum was founded by Mission Team Alpha, later the Primes, using a thousand embryos genetically modified to have Nightblood to protect against solar radiation. The population of Sanctum grew in number during the following two hundred years, yet their demographic growth appears to have been hindered by the Oblation, instated by Josephine Lightbourne to prevent the Nulls from multiplying, the sacrifice of numerous hosts to the Primes, as well as the schism with the Children of Gabriel and the ensuing war. While the Primes originally had a thousand embryos, the remaining embryos were eventually destroyed by Gabriel in an attempt to stop the resurrections of the Primes.
The exact number of citizens, Royal Blood carriers and Nulls who are living in Sanctum is unknown, but several hundred could be seen in attendance during the Naming Day of Delilah Workman in "The Face Behind the Glass". However their number was reduced after "The Blood of Sanctum" due to the Adjustment Protocol massacre. Though Clarke and her friends saved as many people as they could, it is unknown how many citizens died in the massacre.
Children of Gabriel Edit
- Main article: Children of Gabriel
It is revealed in "The Children of Gabriel" that there is another colony living on the moon in the woods. There are a few dozen people distibuted in small groups, but the exact population numbers are unknown. However their numbers were reduced after the season 6 finale due to the Adjustment Protocol massacre.
