2002 Economic Census Bridge Between 2002 NAICS and 1997 NAICS Structure of Table 2

You are here: 2002 Economic Census Bridge report Structure of table 2

 

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. (All of the figures in this report are based on the 2002 Economic Census. For data covering the year 1997, see Comparative Statistics.)

Table 2 is structured according to 1997 NAICS categories. Table 1 is structured according to 2002 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 2002 NAICS column of Table 2 experienced any change in treatment.

Lines showing a number in the 1997 NAICS code column (also shown with a yellow background) refer to that industry as a whole.

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

Example 1

1997 NAICS code	2002 NAICS code	Pt.	Description	Estab- lish- ments	Sales		Annual payroll ($1,000)	Paid employees
					($1,000)	(Pct)
44122			Motorcycle, boat, & other motor vehicle dealers	12,630	32,300,178		3,059,533	104,001
441221			Motorcycle dealers	4,384	14,636,299	100.0	1,429,316	46,037
92% of	441221		Motorcycle dealers (pt)	4,384	14,636,299	100.0	1,429,316	46,037
441229			All other motor vehicle dealers	2,723	5,310,165	100.0	478,833	18,040
9% of	441221		Motorcycle dealers (All-terrain vehicle and personal watercraft dealers)	514	1,353,829	25.5	106,681	4,188
all of	441229		All other motor vehicle dealers	2,209	3,956,336	74.5	372,152	13,852

If only a part of the 2002 NAICS category is included here, then there is a parenthetical note after the 2002 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 2002 NAICS code that indicates how much of the 2002 category this piece accounts for. In Example 1 above, ATV and personal watercraft dealers have been moved from 1997 NAICS 441229 to 2002 NAICS 441221, and that piece corresponds to 9 percent of 1997 NAICS 441229 as enumerated in the 2002 Economic Census. The "9% of" is also a link to table 1, which shows the entire 2002 NAICS code. All of what is left of 2002 NAICS 441229 was included in 1997 NAICS 441220, so "all of" appears to the left of that 2002 NAICS code.

If you wish to study parts of tables 1 and 2 side by side, you may wish to open Table 1 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:

• 2002 NAICS code (on lines with yellow background)
• Symbol for level of comparability between the 1997 and 2002 categories as defined in the table below.

	(Bridge complete.)	Comparable	NAICS 2002 and NAICS 1997 have the same content.
	(Drawbridge slightly open.)	Almost comparable	Sales or receipts from NAICS 2002 are within 3% of NAICS 1997 sales or receipts.
	(Drawbridge open.)	Not comparable	NAICS 2002 sales or receipts cannot be estimated within 3% from NAICS 2002 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 () presents the total of all such components, as illustrated in Example 2.

The symbol , when it appears in this column, provides a link to the correspondence tables from the official 2002 U.S. NAICS Manual. Industries without this symbol (as in the example below) reflect features of NAICS 1997 introduced too late for implementation in the 1997 Economic Census, which thus are introduced for the first time in the 2002 Economic Census.

Example 2

1997 NAICS code	2002 NAICS code	Pt.	Description	Estab- lish- ments	Receipts		Annual payroll ($1,000)	Paid employees
					($1,000)	(Pct)
54169			Other scientific & technical consulting services	14,247	8,066,777		3,061,146	57,641
541690			Other scientific & technical consulting services	14,247	8,066,777	100.0	3,061,146	57,641
	541690		Other scientific & technical consulting services	14,079	7,606,360	94.3	2,925,761	54,829
	541690	pt	Economic and related consulting services	7,634	3,656,924		1,334,483	23,509
	541690	pt	Scientific and related consulting services (except economic, environmental, actuarial and meteorological)	6,445	3,949,436		1,591,278	31,320
7% of	541990		All other professional, scientific, & technical services (Meterological services (weather forecasting))	168	460,417	5.7	135,385	2,812

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 1997 NAICS code. Where there are multiple 2002 NAICS components, the figures add to 100 percent. The figures in this column of table 2 correspond with the "% of" figures in table 1 that link back to this table.
