Good professional practice imposes the obligation upon all public opinion researchers to include, in any report of research results, or to make available when that report is released, certain essential information about how the research was conducted. At a minimum, the following items should be disclosed.

1. Who sponsored the survey, and who conducted it.

2. The exact wording of questions asked, including the text of any preceding instruction or explanation to the interviewer or respondents that might reasonably be expected to affect the response.

3. A definition of the population under study, and a description of the sampling frame used to identify this population.

4. A description of the sample design, giving a clear indication of the method by which the respondents were selected by the researcher, or whether the respondents were entirely self-selected.

5. Sample sizes and, where appropriate, eligibility criteria, screening procedures, and response rates computed according to AAPOR Standard Definitions. At a minimum, a summary of disposition of sample cases should be provided so that response rates could be computed.

6. A discussion of the precision of the findings, including estimates of sampling error, and a description of any weighting or estimating procedures used.

7. Which results are based on parts of the sample, rather than on the total sample, and the size of such parts.

8. Method, location, and dates of data collection.
