All the Rioting That's Fit to Print: Selection Effects in National Newspaper Coverage of Civil Disorders, 1968-1969

This study examined selection effects in newspaper reports about civil disorders in the late 1960s. A comprehensive set of events recorded in newspapers across the United States was compared with the subsets of these events recorded in two national newspapers often used to construct collective event data bases-the New York Times and the Washington Post. The results demonstrate that fewer than half of all disorders are covered in these two newspapers combined, and that those reported are selected on the basis of event intensity, distance, event density, city population size, type of actor, and day of the week. To demonstrate the effects of these selection patterns on substantive analysis of civil disorder, the authors replicated earlier studies using all reported events, and then repeated the analyses using only the events reported in the Times and the Post. This procedure showed some substantial differences in results. The implications of these findings for event analyses and for substantive understandings of media selection are discussed.
