Beginning in 1997 the U.S. Department of Commerce began the
adoption of collecting, computing and reporting economic
statistics based on the NAICS (North American Industry
Classification System) system. The NAICS system is a direct
replacement of the previous SIC (Standard Industry
Classification) system. With the advent of the NAICS system
many new categories were created and many of the existing
categories were re-categorized. Hence it is very difficult if
not impossible to continue looking at statistics based on one
system or the other. MHIA attempted to maintain the continuity
of figures since 1997, but it has become apparent that,
continuing so would not accurately reflect what is being
reported.
Thus you will notice that there are two options, shown
below, for viewing the value of product shipments. The first
option is based on the SIC system and includes data for the
years 1987 through 1996. The second option is based on the
NAICS system and includes data since 1997. In many instances
you may be able to find listings for the same segment in both
options and be able to see history back to 1987, but in other
segments, new categories will have been created and thus a
connection back to 1987 will not be possible.
