How do people survive under the circumstance which was no food and very cold weather almost for 3 months? It must have been very serious and horrible experience they had to eat the human body even dead body.
It happened in 1846-1847. Donner party was a group of American pioneers who set out for California in a wagon. They had to spend winter in Nevada.
They didn’t have enough food, and then they ate human body. At first, there were 87 people in that party. Out of 87, only 47 people were survived. We would like to figure out that what factors affected to this cannibalism. There should have been several factors for survival.
Who were the survivors? How could they survive?
What was the difference between the lived and the died?
Why did the young bachelors all die? Did the dead men really die naturally?
< Hypothesis >
In the extreme situation, who was the most likely to die? Who could have survived? Did you know how could they survive?
Most of people who have own family in bound could have survived more than some singles, especially bachelors.
The reason is they could try to protect their family against the others. They could have been more mutual protection and helped their family and might have killed other people to eat by collusion.
Bachelors might be killed or abandoned their instinct of self-preservation because they might not have hope for one’s survival.
Children who were younger might not be survived.
Some of boys might have been killed as food.
Women with their family could avoid being killed, because they had an ability which can support their family and they were protected by their husband. In result, Men could have died than women. But fathers of families could have survived for protecting their family.
Correlation between Family and survive( ◎ )
▶ Most of 4 families are survived
▶ mutual protection ?
▶ The bachelors might have been killed?
Correlation between gender and survive( ○ )
▶ 2/3 Women survived…2/3 Men died
▶ Protection by men ?
▶ Women could avoid being killed?
Correlation between age and survive ( △ )
▶ 4 girls and 4 boys, aged 3 and under, died
▶ 6 boys, aged 4~16, died
▶ 2 girls, aged 4~16, survived
▶ Some of boys might have been killed?
Possibility of collusion ?
▶ 4 fathers of families survived.
▶ Why did young healthy bachelors die?
▶ But, Why were the dead-time s different?

Mortality by Age Group
| Died | Survived | Total |
Adults | 25(56%) | 20(44%) | 45 |
Children | 15 (36%) | 27(64%) | 42 |
Mortality by Gender
| Died | Survived | Total |
Male | 30(57%) | 23(43%) | 53 |
Female | 10(29%) | 24(71%) | 34 |
<Hypothetic Conclusion>
▶ They ate the only dead bodies at the first time
▶ They might have colluded to kill
▶ Victims mainly were children and the old
▶ They might have evaded to kill families
▶ Young bachelors might have participated the collusion at the first time.
▶ But, most of them might have become victims later
▶ Some of them were dead naturally. (exception)
