Public support for individual and media rights of freedom of expression was examined in this study. Data were analyzed from a national probability sample of 1,508 adults, with items pertaining to freedom of expression formed into two indexes: media rights and individual rights. These indexes were used as dependent variables to test hypotheses based on the demographic variables of sex, age, education, and political orientation. Results indicated that: (1) men supported both rights significantly more than women, with greater disparity for media rights; (2) support for freedom of expression was higher at the left side of the political spectrum than the right; (3) as education increased, support for rights tended to increase, while increasing age seemed to be associated with decreasing support; and (4) three-way interactions between sex, education, and age and between political orientation, education, and age showed relationships to support for expressive rights.
