When the basic sampling unit in the population is to be found in groups or clusters, e.g. human beings in households, the sampling is sometimes carried out by selecting a sample of clusters and observing all the members of each selected cluster. This is known as cluster sampling.

If the elements are closely grouped they are said to be compact. If they are almost equivalent to a geographically compact group from the point of view of investigational convenience they are said to quasi-compact.
