Parties that defend the interest of one or a few ethnic groups and/or regions are, despite their differences, recurrently grouped together into a single party family. This article systematically applies the multidimensional framework offered by Mair and Mudde in order to provide an up-to-date inventory of the universe of ethnic and regionalist parties in Western Europe and assess whether they form a family. The evidence indicates that although the ethnic and regionalist family appears to be somewhat less coherent than more established families, there are clear similarities between the proposed (core) member parties. More specifically, the common denominators that distinguish the members of the ethnic and regionalist party family are their rather similar origins, sociologies, and policy orientations.

西欧的民族和地区主义政党：政党大家庭？

捍卫一个或几个民族和/或地区利益的政党，尽管存在分歧，但经常被归为一个政党大家庭。本文系统地应用了 Mair 和 Mudde 提供的多维框架，以提供西欧种族和地区主义政党的最新清单，并评估他们是否组成一个家庭。证据表明，虽然种族和地区主义家庭似乎比更成熟的家庭缺乏凝聚力，但提议的（核心）成员政党之间有明显的相似之处。更具体地说，区分种族和地区主义政党家庭成员的共同点是他们相当相似的起源、社会学和政策取向。
