The Statistics on Migratory Movements, first published in 1988 and annually ever since, contain municipal migratory figures by origin or destination, and their aim is to annually compile the migratory flows from the counties and municipalities of Catalonia. The Statistics on Changes in Residence in Catalonia are produced on the basis of the registrations and cancellations due to changes of residence that local councils send to the National Statistics Institute (INE) on a monthly basis. For the first time Idescat has published the origin-destination matrix of county migrations, which can be found at Migracions dins de Catalunya. Per comarca de procedència i de destinació
