2002 Economic Census
Bridge Between 2002 NAICS and 1997 NAICS
Structure of Table 1

2007 Economic Census data are
available in American FactFinder.
See also the current Industry Statistics Sampler.

 

This data set details two kinds of changes: (a) between NAICS 2002 and NAICS 1997 and (b) features of NAICS 1997 introduced too late for implementation in the 1997 Economic Census, and thus appearing for the first time in the 2002 Economic Census.

Table 1 is structured according to 2002 NAICS categories. Table 2 is structured according to 1997 NAICS categories. Industries with no changes between 1997 and 2002 are not shown or shown only for reference, to put changing categories in context. Only those industries with codes present in the 1997 NAICS column of Table 1 experienced any change in treatment.

Lines showing a number in the 2002 NAICS code column (also shown with a gray background) refer to that industry as a whole.

Lines showing a number in the 1997 NAICS code column (also shown with a yellow background) refer to that part of the 1997 NAICS that is classified in this 2002 NAICS category.

If only a part of the 1997 NAICS category is included here, then there is a parenthetical note after the 1997 NAICS title in the "Description" column. That note may describe the part, or may only be (pt). On such lines, a figure is shown to the left of the 1997 NAICS code that indicates how much of the 1997 category this piece accounts for. In Example 1 above, adjustment bureaus have been moved from 1997 NAICS 561491 to 2002 NAICS 561440, and that piece corresponds to 2 percent of 1997 NAICS 561491 as enumerated in the 2002 Economic Census. The "2% of" is also a link to table 2, which shows the entire 1997 NAICS category 561491. All of 1997 NAICS 561440 is included in 2002 NAICS 561440, so "all of" appears to the left of that 1997 NAICS code.

If you wish to study parts of tables 1 and 2 side by side, you may wish to open Table 2 in a new browser window (right click on the link), and adjust window sizes so that you can see both at the same time.

2002 NAICS code

This column shows two kinds of information:

1997 NAICS code

This column shows two kinds of information:

Symbol for comparable categories (Bridge complete.) Comparable NAICS 2002 and NAICS 1997 have the same content.
Symbol for almost comparable categories (Drawbridge slightly open.) Almost comparable Sales or receipts from NAICS 1997 are within 3% of NAICS 2002 sales or receipts.
Symbol for noncomparable categories (Drawbridge open.) Not comparable NAICS 2002 sales or receipts cannot be estimated within 3% from NAICS 1997 data.

Pt.

In some cases additional detail was collected, beyond the lowest common denominator between the 2002 and 1997 NAICS categories. These components are identified by "pt" in this column. A separate record, identified with a summation symbol (Summation symbol) presents the total of all such components, as illustrated in Example 2.

The symbol Link to NAICS correspondence table provides a link to the correspondence tables from the official 2002 U.S. NAICS Manual. Industries without this symbol reflect features of NAICS 1997 introduced too late for implementation in the 1997 Economic Census, and thus are introduced for the first time in the 2002 Economic Census.

Description

This column includes the title of the NAICS code (2002 or 1997). The title is linked to the formal, paragraph-style definition of the code. Where only part of the 1997 NAICS category is included there is a parenthetical note. For many industries, this is simply (pt), but in other cases the component is described.

Pct (Percent of sales, receipts, or value of shipments)

This column presents a vertical percent distribution of sales, receipts or value of shipments within each 2002 NAICS code. Where there are multiple 1997 NAICS components, the figures add to 100 percent. The figures in this column of table 1 correspond with the "% of" figures in table 2 that link back to this table.
