A study domain is a major segment of the population for which separate statistics are needed.

A domain could consist of a geographical area such as a region or major population centre. It could also comprise a specified population category, such as a major national or ethnic group. The number of domains has an important bearing on the size and distribution of the sample.

Normally, statistics are presented for different sub-groups of the population, so called study domains. These study domains can be geographical as well as non-geographical. Often these sub-groups are according to some classification (e.g. territorial units, economic activity etc.) (Eurostat, “Assessment of Quality in Statistics: Glossary”, Working Group, Luxembourg, October 2003).

In the course of tabulation, data may actually be provided for many population segments; however, a study domain would be a segment identified in the overall statistical plan as one for which a certain level of detail and certain data reliability were required. The study domains chosen may co-incide with the strata adopted for stratified sampling or may cut across them.
