The document discusses an evaluation of the effects of the Neighbourhood Law ("Llei de Barris") in Barcelona on the health and well-being of residents. The evaluation had three parts: 1) using concept mapping to understand changes in three neighborhoods as perceived by residents, 2) analyzing health surveys from 2001-2011 to study effects on self-rated health and mental health in intervened vs. non-intervened neighborhoods, and 3) proposing a knowledge development paper. Preliminary results found improvements in self-rated health and mental health in intervened neighborhoods, especially among women and those from manual social classes. Overall, the evaluation aimed to understand how urban renewal programs can impact neighborhood health outcomes.
