NOTES: Transportation major groups excluded from ranking. Major groups differ from the sectors used in the TSAs in that they classify all service sectors into a single service group. Additionally, the utilities and communications sectors are classified as a single group.
a For-hire truck transportation in 1992 (under both the 1992 and 1997 classification) includes courier (except air courier) services. Courier services are not included in the 1997 estimate of for-hire truck transportation. For-hire truck transportation in 1992, under the 1992 procedure and 1992 classification, includes warehousing and storage.
b In estimating the 1992 TSAs per the 1997 procedure, natural gas transportation was moved from the utilities to the pipelines sector as natural gas transportation was classified under the pipelines sector in 1997 and hence considered a for-hire transportation mode.
c Nominal 1992 dollars adjusted using the current series, annual consumer price index (CPI) published by the U.S. Bureau of Labor Statistics for all transportation. In 1992, CPI for all transportation was 140.3 and in 1997, the CPI for all transportation was 160.5.
d In-house truck in 1992 also includes in-house bus operations as these two operations were estimated together in the 1992 TSAs.
e Total transportation in 1992 consists of all for-hire transportation and in-house bus and truck transportation under the 1992 procedure and 1992 classification. Under the 1992 procedure and 1997 classification, total transportation in 1992 consists of all for-hire transportation and in-house truck transportation. In 1997, total transportation consists of all for-hire transportation and in-house air, rail, truck, and water transportation.
