Nonsampling Errors
For a general discussion of nonsampling errors, see Nonsampling Errors in Surveys by Judith T.
Lessler and William D. Kalsbeek (New York: John Wiley & Sons, 1992).
While the full extent of nonsampling errors is usually unknown, a variety of related research has been conducted for the SESTAT surveys. Some of the information from this research has been summarized in the technical notes associated with the SESTAT data elements, accessible through the SESTAT Home Page.
