The list of references is the product of a research effort put forward by Matteo Bassoli and Clément Luccioni, with the support of Refugees Welcome International. Aiming at maximal exhaustiveness, the bibliography is the product of the systematic literature review (Bassoli and Luccioni, 2023) based on the PRISMA approach. The original dataset included 75 documents.
URBES research team implements a similar procedure screening post-2020 publications and keeps the dataset updated.

Refugees Welcome International provides a vast amount of grey literature, along with dissertations and other works produced by national chapters or activists.
