The Index of Coincident Indicators in Manufacturing is a numeric index composed of different indicators of high significance in the economic structure of the manufacturing sector and based on a methodological and empirical basis in the development of high-frequency (monthly) indicators to measure the Economic State of a sector or of the economy in general. The formula is based on the standard methodology developed by the Federal Department of Commerce and which was expanded and revised by the Conference Board, the leading entity in charge of computing composite indices in the United States and for other countries. The index is seasonally adjusted, allowing for monthly comparisons, as well as being adjusted for prices (those components expressed in monetary terms), productivity and technological changes. The index dates from 1960 to the present.
