Survey Sampling and Estimation Techniques

Current Research This section of POQ is reserved for brief reports of research in progress, discussions of unresolved problems, methodological studies, and public opinion data not extensively analyzed or interpreted. Succinct case histories are welcomed, as well as hypotheses and insights that may be useful to other students of public opinion. Usually, material in this section is shorter, more informal, and more tentative than in preceding pages.
