Appendix B: Fishing Industry Data
2001 Employment And Payroll By NAICS Codes
Until 2001, the Federal Government used SIC codes to classify the range of industries for
which data was compiled. As of 2001, they system changed to the NAICS system, which
provided a more detailed breakdown of industry sectors, giving a better picture of our Ocean
Sectors. Past information has now been reconfigured to allow back year comparisons
according to these new NAICS categories. The California Economic Development
Department provides the record of employment and wages for workers covered by
unemployment insurance programs from 1997 to 2001. Although these data are not the
official estimates, they offer a benchmark for future research analysis. Additionally, some of
the data are at the county level, which make detailed analysis possible. Table B-1 through B-
-3 present the results of commercial fisheries, seafood preparation and packaging, and
aquaculture industries by county and by NAICS codes. 57
57 After 2000, all industries are classified by BLS using the North American Industry Classification System (NAICS)
rather than the Standard Industrial Classification (SIC). NAICS uses a production-oriented approach to categorize
economic units with similar production processes. NAICS focuses on how products and services are created, as
opposed to SIC which focuses on what is produced. Using NAICS yields significantly different industry groupings
from those produced using SIC. Due to these differences in NAICS and SIC structures, NAICS data will not be directly
comparable to the SIC-based data for earlier years.
BLS is currently in the process of transferring the previous SIC-based employment and payroll data to the new NAICSbased
data. During this transitional period, we are not able to present historical employment and payroll data by
NAICS codes. However, it does not affect our analysis in the previous sections since we compared historical data of
1990 and 2000 based on SIC industries. 2001 employment and payroll data are available by NAICS code.
