    Starting position and origin of the initiative

    El embrión del modelo fue el proyecto “Padrón”, documento en poder de las administraciones locales y el más necesitado por la Generalitat, y el proyecto “TFN-Título de familia numerosa”, documento en poder de la Generalitat y el más necesitado por la administración local. Hoy son más de 700 los ayuntamientos adheridos, representan el 85.24 % de la población catalana y durante lo que va de año ya se han realizado más de 650.000 consultas. También ha actuado como embrión el sistema de consultas de datos tributarios que se estableció entre la Generalitat de Catalunya y la AEAT el 2004 al cual se sumó el Ayuntamiento de Barcelona en el 2006.

    • The Project's success depends largely on the will of collaboration the AAPP and public bodies.
