The flow of ideas between the United Kingdom (UK) and the United States (US) includes approaches to housing policy, as the public sectors in both countries have turned toward the private sector to help provide affordable housing and support redevelopment activities. The Urban Institute and the Institute for Community Cohesion developed an innovative program of work to compare approaches to community revitalization, community cohesion and sustainable neighborhoods in cities across both countries. Ultimately, the purpose of the project is to influence policy and practice agendas in the UK and US by highlighting effective strategies for revitalizing communities and building community cohesion. This report describes the project, discusses contextual differences between the two countries that affect subsidized housing, and highlights lessons drawn from the exchanges that took place during the spring and summer of 2008.
