The City Audit Toolkit offers practical, tested guidance and inspiration to help cities to assess their progress in key areas of third country nationals and migrant integration. The toolkit is designed primarily for people working in local authorities. It contains methodologies for a series of participatory, multi-stakeholder activities like focus groups, photovoice, city integration checklist, aiming to provide a current picture of the city’s main success and challenges to integration, and to indicate concrete issues to be addressed. The toolkit is ready to be shared and adapted by the diverse range of actors and people that want to make their cities more integrating and inclusive.
