Sanctuary city success? How attitudes towards irregular migrants and urban policy differ in Barcelona

In 2012, Barcelona City Council introduced a new city agency that would provide housing and resources for migrants and refugees living within their city-irregular migrants. This esteemed sanctuary city policy further integrated irregular migrants into city life; however, how did natives respond to this effort? Through a difference in differences methodological approach and public opinion survey data from 2008 to 2017, I provide evidence of more positive native attitudes towards irregular migrants and immigration policy. I speculate that the increase in positive perceptions occur due to contact theory. While a single-case study, these findings provide hope for how city governments feeling the burden of the ongoing refugee crisis can adequately provide support for their irregular migrant populations without fear of backlash from their citizens.
