Survey Respondent Information

You’ve been contacted by the University of Delaware’s Center for Applied Demography & Survey Research Center (CADSR). We greatly appreciate your participation in the important research projects we conduct. Please read below for answers to frequently asked questions.

What and who is the Survey Research Center?
CADSR provides a resource for both the University of Delaware and state researchers in Delaware to collect data for their survey research projects.

I received a letter/email, what does that mean?
If you’ve received a letter or an email from CADSR, it is likely that you are being notified in advance that a researcher would like to contact you for participation in a survey. The letter should identify the research project’s name, the name of the researcher responsible for the project, and explain the background of the research project and what you will be asked to do. There should be a phone number and email address that you can use to contact CADSR for more information.

I was contacted by phone, what does that mean?
If you’ve received a phone call or voice mail message from CADSR, we are most likely inviting you to participate in a research project or trying to conduct a survey over the phone. The interviewer calling you should have provided the name of the project and a direct phone number to reach staff associated with the project.

What if I am not sure which project I'm being contacted for?
Please contact our office and we will be happy to help you. You can email Dr. Tibor Tóth at

How did CADSR get my name, address, or phone number?
The research projects conducted by CADSR have a variety of sources for the names of invited participants and their contact information. For instance, perhaps you participated in an earlier component of a project and the associated researcher would like to conduct a follow-up interview. On other projects your phone number may have been randomly generated. On yet other projects, your membership in some population may explain why you were invited (member of an organization, licensed to practice in Delaware, a resident of a specific county, etc.).
If you received a letter or email, the source of your contact information may be included. Likewise, if you are contacted by phone, the research assistant calling you can provide this information.

Who is in charge of CADSR?
CADSR operates under the leadership of its Director, Edward Ratledge.

Delaware Travel Monitoring System Study
This study is conducted for the Delaware Department of Transportation (DelDOT). It provides useful information to policy makers within DelDOT to determine the need for transportation services throughout the State. In addition, the data are spatially mapped utilizing GIS software to provide detailed information for infrastructure planning. Specifically we collect information on ~ Travel patterns ~ Commute times ~ Mode of transportation (e.g. driving, biking, walking, etc) ~ Assess the use and need for public transportation.
