Protest activities can be studied from two angles or levels of analysis: as aggregate-level collective phenomena or as individual-level expressions of political will. This bibliography focuses on individual protest participation. Moreover, in order to further delimit the field, works are prioritized that refer explicitly to protest participation, therefore overlooking proximate terms and phenomena such as activism or participation in social movements. A number of works have examined protest participation in a broader perspective, as one among several modes of political participation. Others have discussed how protest participation can be studied from a methodological point of view.
