About the data

Data on the distribution of manufacturing value added by industry are provided by the United Nations Industrial Development Organization (UNIDO). The classification of manufacturing industries is in accordance with the United Nations International Standard Industrial Classification (ISIC), rev. 2. Manufacturing comprises all of ISIC major division 3.

UNIDO obtains data on manufacturing value added from a variety of national and international sources, including the Statistical Division of the United Nations Secretariat, the World Bank, the Organization for Economic Cooperation and Development, and the International Monetary Fund. To improve comparability of the data over time and across countries, UNIDO supplements originally reported data with information from industrial censuses, statistics supplied by national and international organizations, unpublished data that it collects in the field, and estimates by the UNIDO Secretariat. Nevertheless, coverage may be less than complete, particularly for the informal sector. To the extent that direct information on inputs and outputs is not available, estimates may be employed that may result in errors in industry totals. And there remain differences among countries in the reference period (calendar or fiscal year) and the valuation method (basic, producers’, or purchaser prices) used in estimating value added. See also the notes to table 4.2.

Data on manufacturing value added in U.S. dollars are from the World Bank’s national accounts files. These figures may differ from those used by UNIDO to calculate the shares of value added by industry. Thus estimates of value added in a particular industry group calculated by applying the shares to total value added will not match those found in UNIDO sources.

Definitions

Value added in manufacturing is the sum of gross output, less the value of intermediate goods consumed in production, for industries classified in ISIC major division 3.

Food, beverages, and tobacco comprise ISIC division 31.

Textiles and clothing comprise division 32.

Machinery and transport equipment comprise groups 382–84.

Chemicals comprise groups 351 and 352.

Other manufacturing includes wood and related products (division 33), paper and paper-related products (division 34), petroleum and related products (groups 353–56), basic metals and mineral products (divisions 36 and 37), fabricated metal products and professional goods (groups 381 and 385), and other industries (group 390). When data for textiles, machinery, or chemicals are shown as not available, they are included in other manufacturing.

Data sources

Data on value added in manufacturing in U.S. dollars are from the World Bank’s national accounts files. The data used to calculate share of value added by industry are provided to the World Bank in electronic files by UNIDO. The most recent published source is UNIDO’s International Yearbook of Industrial Statistics 1996.
