All residents whatever their nationalities are invited to register in the Padron, the administrative municipal census, to automatically gain the status of a “neighbour”. The Padron is managed by the local authority (Offices of Citizenship Attention). Access to many services in the city requires registration in the Padron (i.e. for social housing, public education, but also city public bikes). Barcelona registers all persons living in the city, including without an address, allowing irregular migrants, asylum seekers and refugees to access local social services from registration day onwards. In addition, it decreases informality as it ensures the provision of reliable data to public authorities and may help migrants to benefit from proof-of-residence and local activities
