Public opinion research represents a form and extension of public involvement. The traditional forms of public involvement (e.g., town halls, open houses, farmer’s market booths, etc.) are prone to poor attendance, self-selecting participants, the usual suspects, unrepresentative findings, and at times hijacked meetings. Opinion research can assure that public participation really means hearing from a broad cross-section of the community by involving a random pool of citizens. DHM has used telephone and online survey research, focus groups, and large group studies to serve as a complete project or to supplement more conventional forms of public involvement.
