Survey Questions
Introduction
Although there are a number of different sources for prevalence data, surveys are among the sources most commonly used for asthma prevalence. Each survey, however, may have questions that are worded slightly differently, or a survey may change wording from year to year. Wording differences are very important when performing analyses because the differences can affect how respondent answer the question and, therefore, the value of the prevalence measure. The links below will take you directly to a description of data sources with asthma content.
