The aim of the article is to present quantity data collected by the author constituting the basis for the social characteristic of regular activists involved in opposition activities in the 1980s at the local level. It is the result of contemporary sociological studies, in which the author, based on environmental contacts, reached local opposition circles and carried out survey studies. It shows that groups of opposition activists in particular centers were significantly different from the sociological point of view and recruited from different social environments. It seems, however, that in all of the analyzed centers, the activists recruited from persons formerly involved in opposition activities, declaring anti-system attitudes. A characteristic trait common to all former underground activists is their inclination to engage in social activities, which they have retained to this day.
