The UNHCR Microdata Library (MDL) provides access to microdata containing information about UNHCR persons of concern: refugees, asylum seekers, IDPs, returnees, stateless people, and other. The MDL contains unit-level microdata collected directly by UNHCR or indirectly through its partners, but supported in some way by UNHCR. Supporting documents such as metadata, reports, or survey questionnaires are also provided for complementary information on the datasets. The MDL aims to be the reference repository containing metadata on publicly available censuses, administrative data, and surveys regarding forced displaced people and other persons of concern to UNHCR, as well as provide direct access and/or links to the microdata. It is continuously updated as new datasets from UNHCR and its partners become available, and organizations which collect relevant data are highly encouraged to submit datasets for dissemination through the MDL.
