Die United Nations Statistics Division (UNSD) is the custodian of a number of key international classifications, many of which have been maintained since the early days of the United Nations.
The list below provides links to the recent (and previous) versions of the most well-known classifications maintained by UNSD. The publications are often available in several of the official languages of the United Nations system, i.e. Arabic, Chinese, English, French, Russian and Spanish.
There are also additional classifications, now recorded in the International Family of Classifications, that do not exist as separate publications, but are included in other UNSD publications.
The classifications are being maintained by the respective Branches of UNSD.

ISIC is the international reference classification of productive activities. Its main purpose is to provide a set of activity categories that can be utilized for the collection and reporting of statistics according to such activities. Since the adoption of the original version of ISIC in 1948, ISIC has provided guidance to countries in developing national activity classifications and has become an important tool for comparing statistical data on economic activities at the international level. Wide use has been made of ISIC, both nationally and internationally, in classifying data according to kind of economic activity in the fields of economic and social statistics, such as for statistics on national accounts, demography of enterprises, employment and others.
This fourth revision of ISIC (ISIC, Rev.4) is the outcome of a review process that spanned several years and involved contributions from many classifications experts and users around the world. This process resulted in an ISIC structure that is more detailed than the previous version, responding to the need to identify many new industries separately. The relevance of the Classification has been enhanced with the introduction of new high-level categories to better reflect current economic phenomena.

The Central Product Classification (CPC) constitutes a complete product classification covering goods and services. It serves as an international standard for assembling and tabulating all kinds of data requiring product detail, including industrial production, national accounts, service industries, domestic and foreign commodity trade, international trade in services, balance of payments, consumption and price statistics. Statistics based on CPC Version 2.1 are useful in studying transactions in goods and services in detail and as a basis for developing lists of goods and services for specific purposes, such as price statistics surveys. It has broad acceptance as an international standard and facilitates the maintenance of constant categories of products.

This publication provides codes for and descriptions of all of the 2970 SITC, Rev. 4 basic headings and corresponding HS07 subheading codes. In addition, in the three appendices are correspondence tables correlating the following: the subheadings of HS07 to the basic headings of SITC, Rev. 4; the basic headings of SITC, Rev. 4 to the basic headings of SITC, Rev. 3; and the basic headings of SITC, Rev. 3 to the basic headings of SITC, Rev. 4. Many countries and national and international organizations continue to use SITC for various purposes, such as for the study of long-term trends in international merchandise trade and aggregation of traded commodities into classes more suitable for economic analysis.

The original Classification by Broad Economic Categories (BEC) was produced in 1961 to provide a means for international trade statistics to be analyzed by broad economic categories such as food, industrial supplies, capital equipment, consumer durables and consumer non-durables. The original BEC was linked to the Standard International Trade Classification. Two revisions of BEC were produced to coincide with revisions of SITC, and a third revision made technical corrections. The current publication provides links between BEC and the Harmonized Commodity Description and Coding System (2002 edition) as well as to the basic classes of goods in the System of National Accounts (consumption goods, intermediate goods, capital goods). Each of the 3,121 SITC headings is correlated to one of the nineteen BEC basic headings, as are 5,222 of the 5,224 HS02 subheadings (two HS02 subheadings fall outside the scope of SITC, Rev.3 and are therefore not correlated to BEC).

BEC Rev.5 has been completed, but is not yet available on the UNSD publications website.

Classifications of Expenditure According to Purpose: Classification of the Functions of Government (COFOG); Classification of Individual Consumption According to Purpose (COICOP); Classification of the Purposes of Non-Profit Institutions Serving Households (COPNI); Classification of the Outlays of Producers According to Purpose (COPP)
This publication presents four international economic classifications of expenditure according to purpose, COFOG, COICOP, COPNI and COPP, primarily designed to classify transactions undertaken by government, households, non-profit institutions and producers. COFOG is a revised and expanded version of an earlier United Nations document entitled Classification of the Functions of Government (Statistical Papers, Series M. No.70). COICOP, COPNI and COPP were recommended in the 1993 System of National Accounts as international classifications for data compilation and analytical uses, and are presented for the first time in this publication in full detail. These classifications may be used to classify data on purposes of expenditures for the compilation and analysis of statistics on national accounts, consumer price indexes, household and expenditure surveys, government finances, non-profit institutions and producers.
A new version of COICOP is planned for completion in 2018. (COICOP 2018) See UNSC 2018.

This publication sets out provisional guidelines on standard international age classification, as approved by the Statistical Commission at its twenty-first session, in 1981. The guidelines were developed on the basis of existing national practices and international recommendations concerning age classification and the comments made by the members of the Statistical Commission at its twenty-first session. Chapter I explains the purpose of standard international age classifications. Chapter II sets forth recommended standard international age classifications for the following: population; family formation, families and households; learning and educational services; earning activities and the inactive; distribution of income, consumption and accumulation; social security and welfare services; health, health services and nutrition; housing and its environment; public order and safety; time use; leisure and culture; and social stratification and mobility.
