Statistical classifications are logical instruments to systematically and categorically organise the characteristics of a given phenomenon in economics or society according to a classification criterion. One example would be occupations classified by the level of qualifications needed. The purpose of these instruments is to standardise statistics in order to ensure both the spatial and temporal comparability of the statistical information. In the case of Catalonia, they also contribute to advancing the linguistic normalisation of Catalan.
Statistical classifications are grouped by thematic types called "families", and the main families are the economic classifications (economic activities and products) and demographic and social classifications (occupations, education and health).
They categorise the productive units according to the type of activity in order to obtain data that allow statistics on production or profitability to be generated.

They are the most appropriate statistical instrument for presenting statistics on education for different countries. The statistical unit examined is based on the educational curriculum, for which three different aspects are taken into account: the level of education, the educational attainment level and the fields of education.

These are a sub-product of the general classifications of products and are used to measure the expenditures on end consumption by families, public administrations or other institutions. These classifications are also part of the overall harmonisation process of statistical classifications, and the institutions that generate these statistics are either specialised in the subject or international organisations in the given sector.
