Many Sri Lankan migrants chose Italy as a permanent working and living destination. This led to the creation of a large and consolidated community over the last 30 years of which no comprehensive social scientific research has been conducted. In this sense, the Italian case is fairly peculiar if compared to other Western destinations chosen by Sri Lankan migrants, such as Canada, Great Britain, Switzerland, and Germany. In fact, the only studies that deal with Sri Lankans in Italy are concerned with a few communities that settled down in Milan, Rome and Catania. Moreover, there are some general statistics cocerning the foreign presences in Italy which take into account the Sri Lankan immigrants. On this basis we have conducted an explorative research, consisting of interviews with some key persons of the Sri Lankan Diaspora in Italy and an analysis of public statistical data and studies. Yet our mapping is incomplete. It consists of a fairly detailed description of the Sinhalese Diaspora, but largely leaves aside the Tamil one. The main reasons is the much smaller number and influence of Tamils in Italy, as well as the lack of time and resources for doing research on the Tamil groups in the South. Adresses of mayor Tamil groups can be found on page 14. At the heart of the study lies an outline of the main phases of the Sri Lankan immigration to Italy and a mapping of the social structure of this community. It describes locations, employment sectors, organizations and integration in the Italian society. The mapping aims to give a first systematic overview of the Sri Lankan Diaspora in Italy, hoping to become an orientation-paper for further social research on the Sinhalese and Tamil immigration and for supporting political pro-peace activities by its members.
