Was established in 1966 to act as the central co-ordinating body for industrial activities and to promote industrial development and co-operation at the global, regional, national and sectorial levels.

Refer to the extensive range of prices at which goods and services are valued. These comprise: current or constant prices; market or non-market prices; basic prices; producer's prices; purchaser's prices.

The trend-restored form of the composite leading indicator (CLI) is calculated by multiplying the amplitude-adjusted and ratio-to-trend CLI by the trend of the reference series to obtain the trend restored CLI. This trend-restoration enables direct comparison with the reference series.

An index number property such that the algebraic product of the price index comparing period j with period i and the price index comparing period k with period j is equal to the price index that compares period k directly with period i.

A customary approach is to construct such prices by analogy with known market prices established under conditions that are considered essentially the same.

The prices actually paid by consumers to acquire goods or services.

The index number property that makes the relative importance of each transaction involving the purchase of a final product dependent solely on its magnitude and not on the size of the country in which it occurred.

Tourists are persons who do not reside in the country of arrival and are admitted to that country under tourist visas (if required) for purposes of leisure, recreation, holiday, visits to friends or relatives, health or medical treatment, or religious pilgrimage. They must spend at least a night in a collective or private accommodation in the receiving country and their duration of stay must not surpass 12 months.

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

“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.
