Years of Potential Life Lost (YPLL)
YEARS OF POTENTIAL LIFE LOST (YPLL)
The statistic known as "years of potential life lost" (YPLL) is a measure of the relative impact of various diseases and other lethal forces on a population. It is a useful way to draw attention to the loss of expected years of life due to deaths in childhood, adolescence, and early adult life. Injury-related deaths that affect predominantly young males cause as many lost years of potential life expectancy as cancer, which is mainly a disease of older people, even though cancer may cause more deaths. For instance, in Canada in 1993, injuries killed 10,286 people and cancer killed 25,687 people—yet cancer caused 302,585 YPLL, whereas injuries caused 336,593 YPLL.

Encyclopedia.com gives you the ability to cite reference entries and articles according to common styles from the Modern Language Association (MLA), The Chicago Manual of Style, and the American Psychological Association (APA).
Within the “Cite this article” tool, pick a style to see how all available information looks when formatted according to that style. Then, copy and paste the text into your bibliography or works cited list.
Because each style has its own formatting nuances that evolve over time and not all information is available for every reference entry or article, Encyclopedia.com cannot guarantee each citation it generates. Therefore, it’s best to use Encyclopedia.com citations as a starting point before checking the style against your school or publication’s requirements and the most-recent information available at these sites:
Modern Language Association
The Chicago Manual of Style

- Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most Encyclopedia.com content. However, the date of retrieval is often important. Refer to each style’s convention regarding the best way to format page numbers and retrieval dates.
- In addition to the MLA, Chicago, and APA styles, your school, university, publication, or institution may have its own requirements for citations. Therefore, be sure to refer to those guidelines when editing your bibliography or works cited list.
