Changes in Telephone Survey Nonresponse over the Past<br />
Quarter Century. Public Opinion Quarterly 69: 87-98<br />
Nonrespondents are commonly divided into three groups:<br />
• those never reached (noncontacts),<br />
• those unwilling to cooperate (refusals),<br />
• and all others, composed mainly of those for whom it<br />
would have been difficult or impossible to cooperate<br />
(for example, those with language or hearing barriers).<br />
