A Preview of the 1997 Benchmark Input-Output Accounts
New Detailed and Summary Industries
In December 2002, BEA will release the 1997 benchmark
input-output (I-O) accounts of the United States, the
ninth in a series of benchmark accounts. The last bench-
mark accounts were for the year 1992 and were released
in November 1997.
The list of industries provided with this note repre-
sents the level of detail that will be used in the presenta-
tion of the 1997 benchmark I-O accounts. As reported in
a note in the December 2001 S

the 1997 benchmark accounts will present industries on
the basis of the 1997 North American Industry Classifica-
tion System (NAICS), which has replaced the 1987 Stan-
dard Industrial Classification (SIC) system for the
collection and presentation of industry data.

The
NAICS-based I-O industry classification system differs in
structure and format from that used for the 1992 and ear-
lier benchmark accounts.
2
The 1997 benchmark I-O accounts on the NAICS
basis and the 1992 benchmark I-O accounts on the SIC
basis cover about the same number of detailed industries,
but they differ in their coverage of goods-producing
industries and services-providing industries (see the
accompanying table).

The larger number of services
industries in the 1997 benchmark accounts reflects both

3. Goods-producing sectors consist of agriculture, forestry, fishing and
hunting; mining; construction; and manufacturing. Services-providing sec-
tors consist of utilities; wholesale trade; retail trade; transportation and
warehousing; information; finance and insurance; real estate and rental and
leasing; professional and technical services; management of companies and
enterprises; administrative and waste services; educational services; health
care and social assistance; arts, entertainment, and recreation; accommoda-
tion and food services; other services, except public administration; and
government industries. Some industries that were classified as goods pro-
ducing in the SIC system are now classified as services providing in NAICS.
For example, printing and publishing was classified as a goods-producing
manufacturing industry in the SIC system, but is now classified as a ser-
vices-providing information industry. For more information on the NAICS
and the changes in industry classification, see Executive Office of the Presi-
dent, Office of Management and Budget, North American Industry Classifi-
cation System, United States, 1997 (Lanham, MD: Bernan Press).
the increased information that is now available about
these industries and the reclassification of some indus-
tries from goods-producing sectors to services-providing
sectors by NAICS.
Table A, which follows, provides a list of the I-O
industries and their NAICS codes. The summary indus-
tries are shown in bold print, and the detailed industries
are shown in regular print.
The NAICS-based I-O accounts described here and
the SIC-based I-O accounts that are being superseded are
sometimes called alternative I-O accounts.

For 1997, as
in the past, BEA will also produce a second set of I-O
accounts that are sometimes called traditional I-O
accounts. In the 1997 traditional I-O accounts, further
changes to the NAICS industries that have differing and
distinctive production processes will be made. For exam-
ple, in the traditional accounts, lodging services and food
and beverage services that are provided by hotels and that
are presented together in the alternative I-O accounts will
be separated, and food and beverage services will be pre-
sented with the food and beverage industry. Thus, even
though NAICS is a production-based classification sys-
tem, further isolation of industries with distinguishable
production processes is necessary to facilitate Leontief-
type analysis, such as the calculation of total input
requirements (direct and indirect) for each industry from
changes in final demand.
