Death in the Trek: A Study of Mormon Pioneer Mortality

The final stanza of the Mormon pioneer anthem “Come, Come Ye Saints” directly confronts the prospect of dying on the trail: “And should we die, before our journey’s through…”

Now new research shows that pioneer mortality rates were not much greater than national averages at the time.

This may come as a surprise to modern Mormon youth who’ve participated in handcart treks.

“The youth go out and learn that a lot of people died and they push the handcart and after three days they think they are practically dead,” said retired historian Mel Bashore. “But most people traveled in wagons to Utah. The whole Mormon trail movement that spanned 20 years was a really successful endeavor.”

Bashore worked with a team of actuarial scientists at Brigham Young University to analyze 56,000 pioneer records from 1847-1868. Of these 56,000, there were an estimated 1,900 people who died either on the plains or within the calendar year of their arrival. That is about a 3.5 percent mortality rate, whereas a national comparison group in 1850 experienced an annual mortality rate between 2.5 percent and 2.9 percent.

“Everyone knows about pioneers, but what are the data, and what are they saying?” said Dennis Tolley, a BYU statistics professor and co-author of the new study. “This is one of the first definitive analyses with the most up-to-date data regarding how many people there were in this immigration, how many pioneers died, and the breakdowns of these deaths.”

Consulting pioneer journals and family histories, Bashore and Tolley worked with eight BYU students to confirm how many people came over and how many died along the way.

Many of those who died suffered from illnesses common to the time period such as cholera or dysentery. There were also considerable risks from some form of accident along the immigration trail, such as being run over by a wagon, stampeded, or accidentally shot.

Only four deaths reported were from Native Americans, two were eaten by wolves, two suffered a poisonous bite or scorpion sting, and one was murdered.

The pioneers’ mode of travel proved a major factor. Those travelling by wagon saw a mortality rate of 3.5 percent.  But the mortality rate for the roughly 3,000 who traveled by handcart was higher.

The ill-fated Willie and Martin companies suffered a 16.5 percent mortality rate. These two handcart companies left in late July of 1856, and this late departure date led to these companies experiencing many hardships in the winter months with the eventual need for rescue wagons sent from Salt Lake.

Since this story is told so often, there’s a perception that such hardship was the norm.
