Dictionary of Occupation Titles (DOT) is not referenced by
U.S. Census codes.
by David F. Traver
Excerpted from
Social Security Disability Advocate’s Handbook
Some purveyors of reports allegedly addressing the
numbers of jobs that might exist in the economy use “Census codes”
instead of Dictionary of Occupational Titles “numbers.” The
Department of Labor does not obtain information about the existence of
jobs based upon “DOT numbers” and instead uses “Census Codes.”
Some VE’s still testify that Census codes allegedly
contain data about groups of DOT definitions (see Chapter 14 for a
discussion of DOT data). Surprisingly to some, Census codes currently do not
happen to relate to such information. There no longer is a link between Census
Codes and the DOT that is used by the Census Bureau.
The
United States takes the census every ten years
and also changes the census codes every ten years. The Census 2000
classifications were completely revised compared to 1990. Census Codes are now
based on the 1997 NAICS (North American Industry Classification System) and the
1998 SOC (Standard Occupational Classification) coding structures. The
1990 system was based on the 1987 SIC (Standard Industrial Classification
Manual) and the 1980 SOC (Standard Occupational Classification Manual).
Source — Department of Labor.1 There is no longer a link between the
2000 census codes and the revised Fourth Edition of the Dictionary of
Occupational Titles (DOT), which was last updated in 1991.
The SOC was revised because it had not been updated since
1980. The revision was long overdue because of changes in the labor force and in
the way economists view the labor force. Once the revision process was started,
the SOC Revision Policy Committee quickly determined that, due to the extent of
the changes being proposed, it was necessary to redesign the entire SOC. Source

The 2000 Census Bureau’s job codes3 are
different than the codes used in 1990.4 Which census data is the
vocational expert using in your case?
Look at a few of the important differences in the codes
and compare to the codes on the report the VE brought to the hearing. Ask the
following questions:
-
Are the VE’s data are up-to-date?
-
Where did the VE’s data come from?
-
When were they last updated?
-
How were they updated?
-
Did the VE know the census codes she brought to the hearing
were 13-years old?
-
If the report on the VE’s lap says it is for the most recent
quarter of this year, why is that report using 1990 Census codes?
-
How did the publisher of that report use 1990 Census codes
to produce statistically valid and reliable data about today’s jobs?
How does your VE explain this inconsistency and how does
your VE know which DOT codes are associated with the 2000 Census Codes? See
SSR 00-4p. (“When vocational evidence provided by a VE or VS is not consistent
with information in the DOT, the adjudicator must resolve this conflict before
relying on the VE or VS evidence to support a determination or decision that the
individual is or is not disabled. The adjudicator will explain in the
determination or decision how he or she resolved the conflict. The adjudicator
must explain the resolution of the conflict irrespective of how the conflict was
identified.”)5

§1505.3 Census
Occupational Data Limitations
Only the long form census questionnaire asks about
occupation (one in six households get the long form). See Appendix for
sample form.
Two questions are asked. The first identifies the business
or industry. The second question asks for the person’s occupation and what are
the most important duties/activities.
The U.S. Census then has employees review the answers and
assign a “census code” to the occupation, as shown above.
There are currently about 500 separate census codes. This
system is revised and updated every 10 years. There are no exertional
demands identified. There are no skill levels identified
The Census Codes do not reference the Dictionary
of Occupational Titles. Other parties have assigned Dictionary of
Occupational Titles to various 2000 census codes. But these are private
undertakings and are not based upon any empirical review of the work done by the
U.S. Census employees. An example of one of these undertakings is The
Specific Occupation Selector Manual, 4th Ed. (2003), U.S. Publishing, Kansas City, MO.
