| Summary: | Informal business activity is
ubiquitous around the world, but it is nearly always
uncaptured by administrative data, registries, or commercial
sources. For this reason, there are rarely adequate sampling
frames available for survey implementers wishing to measure
the activity and characteristics of the sector. This paper
presents a methodology to generate a representative sample
of informal businesses using an adaptive, geographically
based method called Adaptive Cluster Sampling. Developed for
populations that are clustered and/or rare, this method
helps with efficiently sampling Primary Sampling
Units—blocks—that are fully enumerated, and from which
Secondary Sampling Units—businesses—can be randomly sampled
to conduct interviews. The paper shows how this methodology
can be applied to surveying informal businesses, often
reducing both the average variance of population estimates
and fieldwork effort. Practical considerations and guidance
for implementation and analysis are also provided. |
