What Is the Yearly Probability of Dying?

Yearly probability of dying is a numerical figure that depicts the likelihood of someone dying per year. The yearly probability of dying is determined by looking at a mortality table which shows the rate of death at each age in terms of the number of deaths per thousand. The data in the chart is determined by dividing the number of people dying during a given year by the number of people alive at the beginning of that same year.

Understanding the Yearly Probability Of Dying

The yearly probability of dying is often associated with calculations involving insurance probability estimates. In calculating these death probabilities, some associated terms include instantaneous death, force of mortality and quinquennial (recurring every five years) death probabilities.

Key Takeaways

  • Yearly probability of dying is a number measuring the likelihood a person has of dying per year.
  • This number is often used in insurance probability estimates.
  • The odds of dying increase every eight years throughout life.

Death Never Takes a Holiday

Insurers depend on volumes of mortality data to form the basis for life insurance, disability, annuity, health, and workers compensation policies, to name a few. 

They know, for example, the odds of death from unintentional poisoning by and exposure to noxious substances are 1 in 7,586 in any given year and 1 in 96 over a lifetime. If that seems high, keep in mind this was the leading cause of death by injury in the U.S. In 2014, some 42,000 people died in this manner. For another leading cause of death, pedestrian incidents, the odds are 1 in 6,258 each year and 1 in 647 over a lifetime, according to data compiled by the Insurance Information Institute.

There's more: The odds of dying from an injury in 2014 were 1 in 1,576 according to the latest data available; the lifetime odds of dying from an injury for a person born in 2014 were 1 in 20; the odds of dying from drug poisoning were 1 in 7,586 in 2014; the lifetime odds were 1 in 96 for a person born in 2014, reported iII.

"Heart disease is the leading cause of death in the United States, accounting for 633,842 fatalities in 2015, according to the Centers for Disease Control and Prevention. Influenza and pneumonia ranked eighth in 2015, accounting for some 57,000 fatalities. However, pandemic influenza viruses have the potential to be far more deadly. An estimated 675,000 Americans died during the 1918 Spanish influenza pandemic, the deadliest and most infectious known influenza strain to date," according to the institute.

According to Smithsonian Magazine, your odds of dying increase every eight years throughout life until the odds become a reality. For a 25-year old, the odds of dying are pretty small: 0.03. By the time you reach 100, the odds of living another year are 50/50.
