Quantitative Research

Over many years, I’ve worked with DHM on virtually every type of research as a client, a consultant, and a project partner in such wide-ranging sectors as utility taxes, land conservation community giving and the judiciary. Regardless of circumstance and without exception they've been deep thinkers from the start and deliver unimpeachable work, exceptional analysis, and invaluable insight.

Paul Vogel, Principal, Vogel Communications
DHM research is a highly respected leader in providing independent quantitative opinion research tailored to our clients’ needs. With every project we bring to our clients:
  • More than 40 years’ experience designing and conducting opinion research throughout the Pacific Northwest and United States.
  • Capacity to add value to strategic recommendations by drawing upon decades of extensive work assessing attitudes on a variety of issues.
  • Experience assisting public, private, and nonprofit clients with decision-making, including visioning, strategic planning, program evaluation, budgeting, and communications.
  • Clearly presenting and communicating research findings to diverse audiences, including businesses, elected officials, community leaders, and boards of directors through informative, insightful, and actionable presentations..

Telephone Surveys

For many projects, telephone surveys remain the gold standard when it comes to random sampling and statistical reliability. DHM’s commitment to sound methodology ensures accurate and comprehensive insight. Sampling capability includes cell phones, smartphones, multi-lingual interviews, and database sourcing. 

Online Surveys

The rise in internet penetration and smartphones and the relatively low cost of conducting web surveys have made online survey research an increasingly popular method. Online surveys are ideal when testing visuals, to target younger respondents and hard-to-reach populations, and as community engagement tools. Our online polling platform is easy to use and allows respondents to complete the survey from any device: computer, tablet or mobile phone. Working closely with our programming partners, we integrate complex skip patterns, customize survey responses, use heat mapping, write questions that incorporate the use of images for respondents with limited English proficiency, and find other unique solutions to meet the needs of our clients. DHM was the first firm that used the online MaxDiff technique in Oregon to support policy making, planning, and communications. 

Mail Surveys

Mail surveys provide the widest reach, because almost everyone has a mailing address. In some instances mail surveys provide higher response rates (and perhaps more representative results) than telephone surveys or online surveys. We take explicit steps in the design and administration of mail surveys to assure valid and reliable data.

Mixed Methodology

We use proven research methodologies alongside innovative approaches to meet the unique needs of individual projects. Greater societal changes, including demographic shifts, diminished willingness to participate in surveys, and awareness of the need to give voice to hard-to-reach populations all influence our research methods.

Whether we're combining mail and online research, or live interviews and text-to-online surveys, we are able to customize the mix of approaches best suited to each project. 


The DHM team has deep expertise in analyzing quantitative data and identifying differences in attitudes and behavior by demographic and psychographic (i.e., values, beliefs, lifestyles) subgroups. Our reporting does more than highlight or review results that is easily read from the abstract. Links among demographic characteristics and expressed attitudes are explored and examined. We focus on the implication of those links and how they can develop effective planning, policy making, and communications. Our experts use a variety of advanced inferential statistical methods to uncover meaningful stories in the numbers.
