An age-specific rate is the rate measured in a particular age group. The numerator and the denominator for this rate refer to the same age group, that is, both have the same age distribution. Thus, for instance, the age-specific death rate of persons aged 45 to 64 is:
Age-specific rates are normally used to display aspects of health experience, such as causes of death, for the population of a nation or of jurisdictional divisions such as states, cities, and counties within a nation; they are also used to compare the health and mortality experience among many nations. Usually, these rates are separately tabulated for males and females, to display "age-sex-specific rates," and if the number of cases or events is large enough to generate stable rates, they are further subdivided to display "age-sex-cause-specific rates." For example, trends over time in the death rates from lung cancer among both males and females aged 45 to 64 demonstrate a sharp rise in the rates since the 1950s—first among men, then among women—reflecting the trends in smoking behavior of the two sexes in the second half of the twentieth century.

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:

- 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.
