life-event Defined for the purposes of event-history or life-course analysis, a life-event may consist of any demarcated change in demographic, educational, employment, health, or other individual circumstances locatable to a particular point in time. The temporal sequencing of such events may then be analysed to provide information on the interrelationships between different life-events.

Major events in the life of an individual would include the age of puberty and marriage; the birth of any children; death of a spouse, parent, sibling, or other significant person in that person's life; migration to another region or country; major illnesses; and the onset of physical incapacity in old age. Some would add major events connected with employment, such as getting a job, redundancy or unemployment, any return to further education in adult life, or changes of employer or occupation; others would treat these as secondary events. Life-events constitute significant turning-points in a person's life, in the roles and activities they are encouraged to adopt, and the groups they interact with, and may be associated with changes in attitudes and values.

Learn more about citation styles

Citation styles 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, cannot guarantee each citation it generates. Therefore, it’s best to use 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:

  • Most online reference entries and articles do not have page numbers. Therefore, that information is unavailable for most 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.
