# Introductory aspects

## 1. What are they and what are they for

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.

## 2. Main families

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).

Classifications of economic activities

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.

You may examine the main classifications at Economic activities. Statistical nomenclatures and classifications.

Classifications of products (transportable goods or merchandise and non-transportable goods or services)

They categorise products in order to generate statistics that are related to the transactions to which these goods are subjected (production, foreign trade and transport).

You may examine the main classifications at Products. Statistical nomenclatures and classifications.

Classifications of occupations

They enable statistical data to be gathered that is comparable with the state-wide and international statistics, and they thus help detect different needs or problems, such as unemployment, employment programmes, migration and others.

You may examine the main classifications at Occupations. Statistical nomenclatures and classifications.

Education classifications

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.

You may examine the main classifications at Education. Statistical nomenclatures and classifications.

Consumption classifications

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.

You may examine the main classifications at Consumption. Statistical nomenclatures and classifications.

Classifications in the field of health

The purpose of these statistics is to systematically record, interpret and compare the data on mortality and morbidity gathered in the different countries at different times.
