French Equivalent: Échantillonnage à plusieurs degrés

A sample which is selected by stages, the sampling units at each stage being sub-sampled from the (larger) units chosen at the previous stage.

The sampling units pertaining to the first stage are called primary or first stage units; and similarly for second stage units, etc.

Where the sampling frame has to be constructed in the course of the sampling operation, multi-stage sampling has the additional advantage that only the parts of the population selected at any stage need to be listed for sampling at the next stage.
