The Research Centre for Theology and Religious Studies structures its work and activities along two lines of research with a view to achieving its multi- and interdisciplinary goals. This helps ensure a permanent and dynamic relationship between different researchers and the gathering of new knowledge. In accordance with their subject definitions, the two lines constantly seek to promote research projects to ensure that the desired aims are attained. In addition to the two research lines, CITER has developed the Portal/Observatory «Society & Religion», which was built up on previous work carried out by some CITER researchers. The Portal meets the growing need to produce and update measurable information on the composition of religious identities in Portugal.
