Abstract:	Suppose data for a survey with multistage design is to be collected in two periods. This paper assesses the relative merits of keeping the same clusters in the sample vs. sampling new clusters under different statistical (correlation between clusters and over time) and logistic (costs of survey) scenarios. The design effect of reusing the same clusters from the master sample over time is proportional to the intertemporal correlation of the cluster totals, and inversely proportional to the number of clusters. As long as the efficiency gains are quite minor in the large samples, the usefullness of the designs that reuse the clusters comes from the logistic (cost of the survey) considerations. An empirical demonstration that uses Demographic and Health Survey (DHS) data for Bangladesh, 1996 and 2000, will be provided.
