Content analysis adopts a quantitative, scientific approach to text analysis. Unlike CDA, content analysis is generally focused on texts themselves rather than texts’ relations to their social and historical contexts. One of the classic definitions of content analysis defines it as “a research technique for the objective, systematic-quantitative description of the manifest content of communication” (Berelson, 1952, p. 18). At a practical level, content analysis involves the development of a coding frame that is applied to textual data. It mainly consists of breaking down texts into pertinent units of information in order to permit subsequent coding and categorization.

Krippendorff’s (2013) classic textbook Content Analysis is the standard reference for work in this area. Many of the research design principles and sampling techniques covered in Chapter 5 of this textbook are shared with content analysis, although Krippendorff’s book goes into much greater detail on statistical sampling of texts and units of texts, as well as on statistical tests of interrater reliability.
