Abstract
Comparative political sociology has too often favoured macro-level analyses. In that respect, state borderlines are often regarded as an impassable line for the analysis of the construction of representative political elites. However, this general context is changing, through the transformation of political regimes as well as the construction of a European political arena. The institutionalisation of representative elites at intermediary level, in Catalonia and in Languedoc-Roussillon give sociology interesting field work, regarding the possible measure of the effect of borders on the political staff. In this perspective, comparative analysis of the socio-demographic profiles of Catalan deputies and regional councillors in Languedoc-Roussillon is quite relevant. Indeed, if many similarities can be found in the « objective criteria » regarding the access to political mandates (age, territorial belonging, educational level, socio-economic position), if many similarities can be found in the « objective criteria » regarding the access to political mandates.
