This
directory contains tabulations of employment and wage data for employers
covered under the New Jersey Unemployment Compensation Law. Employment
and wage information up to and including year 2000 data are provided under
the 1987 Standard Industrial Classification System (SIC).
Beginning with the
release of 2001 annual and 2002 quarterly data the program has switched
to the 2002 version of the North American Industry Classification System
(NAICS) as the basis for the assignment and tabulation of economic data
by industry. NAICS is the product of a cooperative effort on the part
of the statistical agencies of the United States, Canada and Mexico. NAICS
provides a common and consistent classification system for the three countries.
Due to major differences in NAICS and SIC structures however, data for
2001 and forward is not comparable to the SIC-based data for earlier years.
NAICS uses a production-oriented
approach to categorize economic units. Units with similar production processes
are classified in the same industry. NAICS focuses on how products and
services are created, as opposed to the SIC focus on what is produced.
This approach yields significantly different industry groupings than those
produced by the SIC approach.
NAICS provides data
users with new industrial groupings that better reflect the workings of
the US and New Jersey economies and will allow for the improved measurement
of new industries. For example, a new industry sector called Information
brings together units that turn information into a commodity with units
that distribute the commodity and units that provide information services.
Information’s major components are publishing, broadcasting, telecommunications,
information services, and data processing. Under the SIC system, these
units were spread across the manufacturing, communications, business services,
and amusement services groups. Another new sector of interest is Professional,
Scientific, and Technical Services. This sector is comprised of establishments
engaged in activities where human capital is the major input.
Some industry sectors
such as Construction will show little employment difference in the migration
from SIC to the NAICS system. However, an industry such as Manufacturing
is likely to show a significant change. For example, companies in the
pharmaceutical industry have been classified in Manufacturing under SIC,
whether or not the locations were engaged in actual manufacturing production.
Under NAICS, employment at pharmaceutical corporate headquarters, will
now become part of a new service-providing sector Management of Companies
and Enterprises, while employment at pharmaceutical research and development
facilities will become part of the Professional, Scientific and Technical
Services sector. While the shift of employment to these new sectors will
result in lower manufacturing employment numbers under NAICS, the level
of overall total industry employment would remain the same.
Note:
Due to a change in the processing of employer information from
the unemployment insurance system, the increase in the number of employers
that have not been classified by industry has been elevated since 1999.
Many of these unclassified employers represent new businesses or employers
who have undergone organizational change. Therefore, industry breakdowns
of units, employment and wages, especially in industries where many new
employers are likely to be concentrated, may be somewhat understated.
NAICS-based first
quarter 2002 data are expected to be available in the spring of 2003.
BUSINESS EMPLOYMENT DYNAMICS (BED)
Business Employment Dynamics (BED) statistics measure changes in employment at the private business establishment level from the third month of one quarter to the third month of the next. In the BED data series, these changes can come about in one of four ways. Gross job gains are defined as increases in employment resulting from expansions of employment at existing establishments or from the opening of establishments. Gross job losses are defined as declines in employment at existing establishments or from the closing of establishments. The difference between the number of gross jobs gained and the number of gross jobs lost is the net change in employment.
The data series on Business Employment Dynamics are derived from the Quarterly Census of Employment and Wages (QCEW), also known as the ES-202 program. This program is a quarterly census of all establishments covered under state and federal unemployment insurance programs, representing about 98 percent of employment on nonfarm payrolls.
BED data also have a more limited scope than the Quarterly Census of Employment and Wages (QCEW) data. The data in this series, in contrast to the QCEW data, exclude government employees, private households (NAICS 814110), and establishments with zero employment. Please see the technical notes for further information.
The
following are downloadable compressed (ZIPPED) files. They contain employment
and wages covered by unemployment insurance for all New Jersey, its 21
counties and its 566 municipalities as of the third quarter for 1991 through
2001. The data are available at the two and four digit Standard Industrial
Classification levels. The files have been compressed using PKZIP. You
will need PKUNZIP 2.04 or higher to uncompress them.
