[1][2] The study documented the linguistic diversity of the 12 original EC countries and later of its newer members who joined the EU.
[7] Later, using those two bibliographical studies as a basis, the European Commission expanded the scope and 4 research centres became part of the project.
[7] These centres organised teams of researchers who did extensive fieldwork and gathered reliable data on the linguistic and socio–economic situation of communities with minority languages resulting in the production of multiple large reports.
[2] The results of the Euromosaic project described communities with minority languages were in areas usually sidelined socio-politically and economically by the state.
[12] The interaction between a language group and the state affected the conditions for linguistic maintenance or disappearance and was dependant on elements such as legitimacy (legislation, social policy), legal status and institutionalisation.
