Statistical Terms Glossary

Value added is a measurement that is related to a production process taken as a whole, that is, a combination of inputs, capital goods, labour and technology, in order to obtain a combination of outputs.

Two alternative views of value added as it relates to tourism can be identified:

- Most simply, the value added of the tourism industries can be estimated as the sum of the value added of each tourism characteristic industry.

- Alternatively, a direct link between the demand for tourism goods and services and their supply can be determined, and value added for a certain level of visitor consumption can be estimated.

“Tourism-connected products” is a residual category, including those that have been identified as tourism-specific in a given country but for which this attribute has not been acknowledged on a worldwide basis.

Tourism-specific products (related to visitor consumption) are the sum of the following two categories:
- tourism characteristic products, and
- tourism-connected products.
The Tourism Satellite Accounts contains a list of tourism-specific products primarily derived from the Central Product Classification, Version 1.0, and expanded, where required, for the analysis of tourism. Other classifications have also been considered, such as the Classification of Individual Consumption by Purpose (COICOP), the Statistical Classification of Products by Activity (CPA) of the European Union, the classification proposed by OECD for the analysis of tourism and also some lists established by national entities for the same purpose. The list is provided in Annex 1 of Tourism Satellite Account: Recommended Methodological Framework
