    Classification Systems

    Gefinor Rotana Hotel, Beirut, Lebanon

    Classification: Why Classify?

    * Classification systems determine empirical economic analysis.

    Classification must therefore be:

    *By meaningful criteria
    *Neither too aggregated nor too fine at the published level
    *Acceptable and comparable across countries
    *Comparable across a sequence of accounts
    *Exhaustive and mutually exclusive
    *Flexible: new codes / satellite accounts

    *Useful in determining sampling units and stratification factors

    * Household expenditure surveys use classifications for budget items that are distinct from standard product classification
    * International: COICOP for HES, CPC for price survey, but a correspondence table exists to map CPC into COICOP

    Using classifications in price statistics

    PPI and construction put in place price index

    *Classification of establishments in business censuses and surveys, including the PPI price survey. Such censuses and surveys would include both government and privately owned establishments engaged in the covered activities. Production and capital formation surveys should use the same product classification to facilitate supply and use analysis.

    *Issue: National business surveys generally use product classifications that are extensions of the industry classification, but as noted in the previous topic, this classification is not used in coding consumer price surveys, which are an extension of the household expenditure classification.
