Description: The total variance of a survey estimate incorporates sampling variance, simple response variance and correlated response variance. The last component reflects the part of the total variance due to a common influence on a group of respondents. In the Canadian census, self-enumeration was adopted as the standard method of enumeration in the 1971 Census. One factor in favor of introducing this method was evidence, from the 1961 Census, that correlated response variance made an important contribution to the total variance of census estimates. Based on a study conducted using interpenetration of interviewers, this article compares correlated response variances from the 1961, 1971 and 1976 Censuses. The empirical results demonstrate that although the self-enumeration adopted in the 1971 Census did not completely remove the correlated response variance, this approach has considerably reduced the magnitude of this component of variance for almost all the characteristics examined.
