r Revised. p Preliminary.
Note. The statistics in this release cover output, capacity, and capacity utilization in the
U.S. industrial sector, which is defined by the Federal Reserve to comprise manufacturing,
mining, and electric and gas utilities. Mining is defined as all industries in sector 21 of the
North American Industry Classification System (NAICS); electric and gas utilities are those in
NAICS sectors 2211 and 2212. Manufacturing comprises NAICS manufacturing industries (sector 31-33)
plus the logging industry and the newspaper, periodical, book, and directory publishing industries.
Logging and publishing are classified elsewhere in NAICS (under agriculture and information
respectively), but historically they were considered to be manufacturing and were included in
the industrial sector under the Standard Industrial Classification (SIC) system. In December 2002
the Federal Reserve reclassified all its industrial output data from the SIC system to NAICS.
