This article charts the changing conceptualization of Travellers in relevant Irish central government policy statements since the s, together with the accommodation policy initiatives devised on this basis. It interprets developments in this regard as a movement from assimilationism to integrationism to (weak) multiculturalism. The article also reveals a significant "policy implementation deficit", which is manifested in two ways. Firstly, accommodation output has generally failed to meet central government targets and has consistently failed to reduce the numbers of Travellers living in unofficial encampments. Secondly, the type of accommodation provided has often been at variance with central government recommendations. Thus, an assimilationist policy statement has effected multicultural policy outcomes, while a multiculturalist policy statement has effected assimilationist policy outcomes. These patterns of accommodation output are related to various implementation variables-some long-standing, others new-which have impeded the implementation of national policy by actors on the ground.
