Description
of Columns Groups and Series: Series with asterisks are included in the published totals but are not published separately. The following abbreviations are used: n.e.c. = not elsewhere classified; misc. = miscellaneous; pt = part. Classification: NAICS codes are from the North American Industry Classification, 2002 edition, published by the U.S. Office of Management and Budget. Individual and aggregate series have been compiled on a consistent NAICS basis back to 1972. Major aggregates and groupings were linked to their corresponding pre–1972 SIC–based counterparts. Market codes are as follows: Consumer goods (C) Nonindustrial supplies (S) Value added: Values and proportions are compiled from information contained in the Census of Manufactures, Annual Survey of Manufactures, and Census of Mineral Industries and in reports from the Department of Energy, the Edison Electric Institute, and the American Gas Association. The figures may not add to totals because of rounding. Type of series: The following codes appear: Prod: Monthly product data, unless otherwise noted. Qprod: Quarterly product data, usually interpolated to the monthly frequency using a cubic spline. Hrs: Production worker hours, data collected by the Bureau of Labor Statistics. Est: Series are estimated by the Federal Reserve until source data can be introduced at an annual revision. Units, source for monthly series, and notes: The source and units for the underlying data for detailed indexes other than for those based on production worker hours or electric power use. Starting dates are shown for indexes that begin in years other than 1972. Coverage
