A model-based synthesis is presented for a number of well-known results concerning
the design effect of cluster sampling. This helps to yield a simpler perspective, making the
design-based expressions more transparent. In particular, it is shown that the use of auxiliary
information removes the extra variance that is due to the variation in the cluster sizes.
Moreover, it can reduce the loss of efficiency to the extent it reduces the conditional intracluster
correlation given the covariates. The design effect then depends on the remaining
conditional intra-cluster correlation and an average cluster size.
