As the term implies, "population density" refers to the number of people in a defined jurisdiction, in relation to the size of the area that they occupy. Obviously, the population density is higher in urban areas than in rural communities. In the world as a whole, the population density is very high in some nations, such as Singapore and the Netherlands, and very low in others, such as Greenland and Australia (though in Australia the density is quite high in several large cities, while the rest of the continent is sparsely settled). Tables showing the population density of the nations of the world are published by the United Nations Statistical Office. While population density is a useful measure, the proportion of people living in urban areas in relation to the area available to produce food for them might be a more meaningful statistic.

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
American Psychological Association
- 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.
