This study provides a picture of the institutional network engaged in the provision of affordable housing in Polk County, what we have termed the Polk County Affordable Housing Network (PCAH Network). It analyzes the web of relationships that structure the network including the number of connections, strength of connections, and degree of influence within the network. Understanding the structure of the PCAH Network and the relationships between the actors will enable funders, decision-‐‐makers, and others engaged in the issue to identify existing knowledge gaps and barriers to innovation and to improve how organizations work together to provide affordable housing in Polk County.
