This article examines the individual and contextual factors affecting peripheral identifications in Spain. It does so by conducting multilevel statistical analyses on two surveys on regional and national identifications that were carried out by the Centro de Investigaciones Sociológicas in 1996 and 2006, at two very different political conjunctures. At the individual level, these analyses show that peripheral identifications are strongly conditioned by language attributes (in particular by vernacular mother languages), by the place of birth of respondents and by left–right self-placements. At the aggregate level, only geographical distance from the national centre exerts a significant and consistent influence on peripheral identifications. Our analysis reveals also that the effects of language attributes and ideological orientations increased from 1996 to 2006, and suggests that contexts of polarisation regarding political–territorial issues strengthen the influence of linguistic characteristics and ideological orientations on peripheral identities.
