The Washington Group Blog

This blog entry provides information on how to train interviewers for dealing with disability in either surveys or censuses. It addresses both the particular issues of asking about disability, and also things to consider when interviewing people with disabilities for any survey.

This blog discusses some basic guidance on how to determine an appropriate sample size for surveys collecting information on people with disabilities. Sample size depends on the purpose of the analysis, the intended degree of disaggregation, and the level of accuracy desired.

Responses to surveys are very sensitive to how questions are worded. This blog summarizes the methodology recommended by the WG for translating the WG question sets in a manner that preserves the reliability of the data collected.
