The basic design of the index is the same as that used in the second edition of the SOC2000.
The index consists of an ordered list of job titles, showing the SOC2010 and SOC2000 unit groups to which the job title is classified.
The numbering system used to define the structure of SOC2010 is described in Volume 1.
The SOC2010 coding index has been compiled so that users can achieve good quality coding to SOC2010.
New index entries have been added and some deleted.
The SOC2000 equivalent of the SOC2010 code has been given but not all of the index entries required for the finer points of coding to SOC2000 have been retained.
Where the link to SOC2000 is known to be less reliable, the SOC2000 code is printed in italics in the published index.
Employment status is needed to derive the social classifications.
Some SOC2010 codes are prefixed by S to denote the employment status of Foreman/Supervisor, which is used in the derivation of the National Statistics Socio-economic Classification.
The coding index for SOC2010 contains 27,966 entries, including 4,228 changes (2,206 additions, 1,210 deletions and 812 replacements) to deal with new job titles, changes in usage and some removal of redundant titles.
Only the SOC2010 code will be given in the examples quoted in these notes.
The index in SOC2010 volume 2 follows the principles and layout style which were first adopted in the Classification of Occupations 1960 to improve the efficiency of clerical coding.
The main principle is listing job titles in reverse word order, for example, ‘School crossing patrol warden’ will be found as:
9244 Warden, patrol, crossing, school
This locates related titles in a single list and with a default code for cases where one code covers many variations.
The index is compiled in this way to improve the accuracy of manual coding.Back to table of contents
All index entries have been examined in the process of allocating them to the groups of SOC2010.
Staff in the Classifications and Harmonisation Unit gathered information on new occupation titles from advertisements for job vacancies and scrutinised queries from all sources to identify changes to update the index.
The main sources are the queries raised from allocating occupation codes to occupational information contained within:
the 2001 Census of Population
the Labour Force Survey
Births and Deaths registration records
Other sources of useful information were the careers websites and a data extract from the Local Government Association.
Extensive and detailed information on job titles and job content was also provided by more than 200 interested organisations.Back to table of contents
As with the second edition of the SOC2000 volume 2, the coding index of SOC2010 (4.4 Mb Excel sheet) is available in electronic format.
This file contains the contents of the coding index.
It is not, however an automated coding package.Back to table of contents
The use of job titles changes over time and new titles are introduced.
The Classifications and Harmonisation Unit seeks to increase its knowledge of jobs, their titles and associated tasks.
SOC2010 users are invited to forward information, which will help in the compilation of the job title index and feed into the work for the next update.

1.1 Indexing word
Job titles are arranged alphabetically under indexing words.
The indexing word is usually the word which describes the core set of tasks that characterise a job. Examples of these are words such as ‘operator’, ‘cleaner’, and ‘attendant’.
However some indexing words are very general terms which give no indication of the work being performed, such as:
1.2 Equivalent words
The feminine form of a job title is not indexed unless it is very common or its coding is different from the coding of the masculine form, so actor is in the index but not actress.
Similarly, use index entries listed as man for ‘woman’ (where there is no index entry for woman) and ‘person’.
1.3 Job titles
Sometimes a job title is just a single word which links exactly to an index entry and therefore is simple to code.
The indexing word is rarely sufficient to enable the job title to be correctly coded.
Frequently an indexing word is made specific by the use of a qualifying term, for example to code, ‘Cake decorator’ use the indexing word ‘Decorator’ and the qualifying word ‘cake’.
1.4 Reverse word order
The entries in the index generally appear in reverse word order, for example:
‘Betting shop cashier’ will be found under
4129 Cashier, shop, betting
1.5 Qualifying terms
In most cases the job title is made specific by words which are called qualifying terms.
There are three types of qualifying terms:
additional qualifying terms
1.6 Occupational qualifying terms
Words shown separated from the indexing word by a comma are called occupational qualifying terms and must precede the indexing word in the job title being coded.
For example, use the index entry:
9272 Assistant, canteen
to code ‘Canteen assistant’
Occupational qualifying terms are indexed in reverse word order, for example the job title ‘Stage lighting technician’ is indexed as:
5241 Technician, lighting, stage
A job title may contain a further qualifying word that is not listed in the index.
For example, there is no index entry ‘Controller, depot, freight’ but the job title ‘Freight depot controller’ is coded using the index entry:
4133 Controller, depot
Similarly, ‘White clay modeller’ is coded from the index entry:
5441 Modeller, clay
and ‘Bank Technician’ is coded from the index entry:
It is important to work in the order of the words. For example ‘Hospital office administrator’ must be coded from:
4159 Administrator, office
3561 Administrator, hospital
Sometimes a job title is recorded with the indexing word written before the occupational qualifying term, for example ‘Controller purchasing’.
Where no other words are recorded in the job title, the corresponding index entry can be used, for this example:
3541 Controller, purchasing
1.7 Compound words
For compound words, such as ‘Groundkeeper’, where the last element is an indexing word, go to the list for that indexing word:
5114 Keeper, ground
and ‘Toolmaker’ is indexed under
5222 Maker, tool
Some very common terms have also been indexed in their natural word order, for example, 'Bricklayer' under letter B and 'Coastguard' under letter C.
1.8 Use of 'ad', 'and', 'at', 'de', 'for', 'in', 'of ', 'on', 'the', 'to'
Some job titles may be qualified by a clause following the indexing word, for example:
2419 Clerk of the court 5434 Chef de partie
Titles like these are indexed in their alphabetical position at the end of the list for the relevant indexing word, but before any hyphenated double-barrelled entries, for example:
3535 Inspector of taxes
is in the clause entries at the end of the Inspector list.
These job titles are usually very specific so the index entries must be used with special care.
For example, ‘Council clerk’ must NOT be coded from the index entry:
1139 Clerk to the council
1.9 Double-barrelled job titles
Sometimes a job title is expressed as two titles connected by a hyphen.
Commonly used hyphenated job titles are listed in the index at the end of the list for the first job title.
Do not reverse the order of the words, so for example to code ‘Fitter – driver’ go to the end of list for indexing word ‘Fitter’ to find
Do not use the second title in the pair which would lead to:
The hyphen can be read as an oblique. For example, ‘Receptionist/ typist’ is coded from:
Where a double-barrelled job title does not appear in the index, look up the first title.
For example, ‘Cataloguer-lister’ is coded from:
Only use the second title if the first is not in the index.
For example, ‘Pestman-fumigator’ is coded from:
See also note 3.4.
1.10 Industrial and additional qualifying terms
These qualifying terms can be more freely interpreted than the strict observance of occupational qualifying terms.
They may be used where they are part of the job title, or where they can be inferred from it, or they may have been provided in answer to a question other than one asking for details of a person’s job title.
Some examples are shown in the notes which follow.
1.11 Industrial qualifying terms
Industrial qualifying terms are shown within brackets and in italics and can take the form of an industry or branch of industry in which the person works.
The abbreviation ‘mfr’ is used to cover manufacturing, making, building and repairing.
The industrial qualifying term government includes both government departments and government agencies at national, regional and local levels.
An industrial qualifying term is used in the example, ‘Tractor driver on a farm’, which is coded from the index entry:
8223 Driver, tractor (agriculture)
Similarly, the job title ‘Furnaceman’ – industry ‘steelworks’ is coded from the index entry:
8117 Furnaceman (metal trades)
1.12 Additional qualifying terms
Sometimes the qualifying term is more easily stated in terms of the type of material worked with, the machinery used or the process involved.
These additional qualifying terms enable a number of specific terms to be summarised in a more general word and are shown in the index within brackets.
Two examples of additional qualifying terms are:
The job title ‘Steel plate moulder’ is coded from the index entry:
5212 Moulder, plate (metal)
The job title ‘Gold leaf cutter’ is coded from the index entry:
5449 Cutter, leaf (precious metals)
Additional qualifying terms can also, in a few cases, take the form of professional qualifications to differentiate between occupations.
Two examples are:
The job title ‘Cost Accountant’ has the following index entries: 2421 Accountant, cost (qualified) 4122 Accountant, cost
The job title ‘Thermal Engineer’ has the following index entries: 2129 Engineer, thermal (professional) 5314 Engineer, thermal
The coder is referred to the Engineer (professional) list so that any information on the professional specialism can be used to reach the appropriate occupation code.
For example, for the job title ‘Marine technical consultant’ go to the index entry:
Consultant, technical – see also Engineer (professional) to use
2122 Engineer (professional, marine)
1.13 Order of qualifying terms
The list for an indexing word may contain some or all types of qualifying terms.
Use the qualifying terms in the order they are listed in the index: occupational, then additional, and then industrial.
1.14 Default index entries
Where a code number appears against an indexing word, the indexing word is used as a default index entry.
The default index entry is used to code all job titles which include the indexing word but which cannot be coded from any of the index entries with occupational, additional, or industrial qualifying terms.
The following examples explain the default convention.
The job title ‘Wedding caterer’ is coded from the default index entry:
because ‘wedding’ is not in the list of occupational qualifying terms and none of the additional or industrial qualifying terms for indexing word ‘caterer’ relate to ‘wedding’.
For job title ‘School laboratory technician’ the default index entry:
3111 Technician, laboratory
is used since none of the other index entries for ‘laboratory technician’ include the word ‘school’.
In the same way, the job title ‘Hospital office administrator’ is coded from:
4159 Administrator, office
because hospital is not in the list of other index entries for ‘office administrator’, the default entry is used.
As mentioned previously, the order of the words is significant. The index entry:
3561 Administrator, hospital
must NOT be used for ‘Hospital office administrator’.
Another example of the use of a default code is the entry:
There are several entries for the indexing word ‘Cleaner’ with occupational, additional and industrial qualifying terms.
The default entry is used when:
(a) none of the qualifying terms apply, or
(b) only the word ‘Cleaner’ has been recorded with NO other occupational, additional or industrial information.
The use of the default entry, as described in item b) above, does not apply when there is an ‘nos’ entry in the list for the indexing word, see 1.15.
1.15 Use of 'nos' – not otherwise specified
An index entry with ‘nos’ listed as an occupational qualifying term is used more precisely than a default index entry.
The abbreviation nos is used to denote that the index entry can only be used where the job title has been recorded without any other information to use as occupational, additional or industrial qualifying terms.
For example the list of index entries for Chemist has a nos entry and a default entry.
The job title ‘Pigment chemist’ is coded using the default index entry:
because the word ‘pigment’ does not appear in the occupational qualifying terms in the list for chemists.
The job title ‘Chemist’ working in the retail trade is coded using the index entry:
2213 Chemist (retail trade)
The job title ‘Chemist’, with no other information, is coded using the index entry:
2213 Chemist, nos
1.16 Use of ‘see...’ and ‘see also...’
Where the list for one indexing word can be used for another indexing word the coder is directed to ‘see...’ or ‘see also...’
These referral statements are used in different ways.
For a job title that has alternative spellings, for example:
Advisor – see Adviser
Where a job title is sufficiently similar in its coding to that of all, or some, of the entries for another job title, for example:
Minder, machine – see also Machinist
A pair of empty brackets indicates words enclosed by brackets, so use only that part of the list with a job title followed by a bracketed qualifying term.
These appear at the end of the occupational qualifying terms, for example:
Manager, section – see Manager ( )
use the manager entries starting at Manager (catering)
The words ‘see also ...’ appear where the coder must check the entries at that point in the index before going to the other list, for example:
1251 Factor, estate (Scotland) 3234 Factor, housing (Scotland: local government) 1251 Factor, housing (Scotland) 1254 Factor, motor Factor – see also Dealer
use the Dealer list only after checking the entries for Factor.
It is common for some job titles to be abbreviated and these abbreviations are indexed at the beginning of each relevant letter, for example:
is the index entry for MEP (which is the abbreviation for Member of the European Parliament) and it is in the list of abbreviations at the beginning of letter M.
is the index entry for PCSO (which is the abbreviation for Police Community Support Officer) and it is at the beginning of letter P.
Sometimes grades or qualifications are used as job titles and written as abbreviations. These are listed in the index.
2412 QC for Queen’s Counsel.
for Member of the Royal College of Veterinary Surgeons.
The abbreviations ‘cnc’ and ‘nc’ are occupational qualifying terms which stand for computer numerically controlled, and numerically controlled.
They are most often used with job titles such as Press Setter, Machine Setter, Programmer and Operator.
1.18 Assistant, Deputy, Principal, etc. as prefixes
Job titles prefixed by words which indicate a position in a hierarchy, for example, ‘apprentice’, ‘assistant’, ‘chief’, ‘departmental’, ‘deputy’, ‘head’, ‘principal’, ‘trainee’, ‘under’, are normally coded as though the prefix words were not present.
For example, the job title ‘Assistant Radiographer’ is coded from:
The job title ‘Assistant Funeral Director’ is coded from:
6148 Director, funeral
There are a few exceptions where the coding is altered by such a qualifying word and in those instances the complete title is indexed, for example:
2429 Secretary, private, principal 4215 Secretary, private
See also note 3.1 for the conventional coding of certain apprentices and trainees, and 3.5 for terms used with Engineer.
1.19 Assistant, Deputy, Principal, etc. as indexing words
As well as prefixing a job title, ‘assistant’, ‘deputy’, and ‘principal’ can also be titles in their own right.
For example, in the job title ‘Chef’s assistant’, assistant is the indexing word so this title is coded using the index entry:
9272 Assistant, chef’s
Similarly, ‘Radiographer’s assistant’ is coded from:
6141 Assistant, radiographer’sBack to table of contents
2.1 Conversion to job title
Occupation information is not always given as a job title and sometimes the response has to be converted before it can be found in the index.
Verbs or parts of verbs are normally converted to nouns, except in the following instances:
For example, ‘engineering’ is not converted to Engineer and ‘banking’ is not converted to Banker but descriptions such as ‘packing’ can be converted to ‘Packer’.
Similarly convert ‘inspection’ to Inspector, ‘repair’ to Repairer and ‘work’ to Worker, except for ‘shop work’ and ‘brick work’.
2.2 The Armed Forces and the Civil Service
Many members of the Armed Forces and, to a lesser extent the Civil Service, have jobs which are unique to those industrial sectors.
The most common job titles for Forces personnel are included in the index, for example:
Where the specific term is not given, for members of the Armed Forces, if officer rank is known, code to 1171, otherwise code to 3311.
Similarly many terms used in the Civil Service will be found in the index.
However, where members of the Armed Forces and the Civil Service give job titles that equate to jobs found outside these organisations, for example, ‘Vehicle mechanic’, ‘Radio operator’, ‘Statistician’, use these titles to code the occupation, rather than rank or grade.
2.3 Diplomatic personnel
Members of foreign or Commonwealth diplomatic staffs are coded 1115.
The word polytechnic is treated as synonymous with university.
If an occupation includes polytechnic use the entry for university.
For example, the job title ‘Lecturer in polytechnic’ is coded from:
2311 Lecturer (higher education, university)
2.5 Teaching staff
Teaching staff are generally coded according to the type of educational establishments where they work.
2311: Higher educational establishments (for example, university, law college, medical school)
2312: Further educational establishments (for example, agricultural college, secretarial college, technical college)
2314: Secondary schools (and middle schools deemed secondary schools)
2315: Primary schools and nursery schools (and middle schools deemed primary schools)
2316: Teachers of children, at different levels of education, who have special needs
2319: Teachers of recreational subjects at evening institutes and similar establishments, and private tutors of music
3563: Vocational and industrial trainers teaching occupational skills
Head teachers and principals of all types educational establishments are now coded to 2317.
This does not apply to assistant or deputy heads.Back to table of contents
3.1 Apprentice/Graduate apprentice/ Management trainee/Trainee
All persons in training for an occupation or profession should be coded to the relevant occupation or profession for which they are training.
In cases where it is NOT possible to determine the occupation or profession for which they are in training, the following conventions apply for these specific cases:
‘Management trainee’ code 1259
‘Graduate apprentice’ code 2129
‘Student apprentice’ code 2129
‘Apprentice’, with no occupational qualifying terms where there is information on industry
construction trades code 5319
electrical trades code 5249
engineering code 5223
where there is NO information on industry
3.2 Foremen, Supervisors and Team Leaders
SOC2010 differs from SOC2000 in that it recognises a specific number of supervisory jobs as distinct occupations, classifying these to a particular unit group.
This occurs within the following unit groups:
4162 Office supervisors
5250 Skilled metal, electrical and electronic trades supervisors
5330 Construction and building trades supervisors
6240 Cleaning and housekeeping managers and supervisors
7130 Sales supervisors
7220 Customer service managers and supervisors
Where the indexing word consists of ‘foreman/woman’, ‘supervisor’ or ‘team leader’, relevant qualifying words should be checked in the index to determine whether or not coding to one of the above unit groups is appropriate.
If the job is not classified to one of the above unit groups, the indexing term is ignored and the job is classified to the occupation being supervised.
For example, the job title ‘Foreman, maker, cabinet’ is coded from index entry:
5442 Maker, cabinet
The job title ‘Clerical supervisor’ is coded from the index entry
4162 Supervisor, clerical
There are no index entries for foreman over particular groups of workers, so for example ‘Foreman of labourers’ is coded from the index entries for Labourer.
The following terms are regarded as synonymous with Supervisor or Foreman:
Boss Chargehand Chargeman Gaffer Ganger Headman Overlooker Overseer Team Leader and also assistant foreman, assistant supervisor, etc.
All these job titles are indexed in their own right but to aid coding also refer to the index entries for Foreman.
Please note Supervisor is not always a synonym for Foreman.
For example when used in the context of supervising children with the job title ‘Playground supervisor’.
3.3 Company Director/Director/Director of /Managing Director
Where ‘Company Director’, ‘Director’, or ‘Managing director’ is recorded without any occupation qualifying terms code as follows:
(a) if any industry information is available code from the Director ( ) entries.
(b) if no match is found from the Director ( ) entries, go to Manager ( ) entries
(c) if no other information is available code to 1259, except Managing director which codes to 1139
The list for indexing word Owner is also used for Partner and Proprietor but where another job title is stated, code to that job title. For example, ‘Owner taxi driver’ is coded from the index entry:
8214 Driver, taxi
The job title ‘Partner bookkeeper’ is coded from the index entry:
The job title ‘Proprietor and hairdresser’ is coded from the index entry:
Where no other job title is stated, refer to the index entries for Owner.
The job title engineer presents difficulty in coding because it is commonly used in a variety of circumstances.
The index includes various job titles for specific engineers that may be used by both professional engineers (usually classified in Major group 2) and by those who are not regarded as professional within the classification.
If the title to be coded is prefixed by the terms ‘advisory’, ‘chief’, ‘chartered’, ‘consultant’, ‘design’, ‘development’, ‘principal’, ‘research’, ‘senior’, it can be assumed that the person is a professional engineer.
A list of professional specialisms is included at the end of the index entries for Engineer.
For example ‘Chief aviation engineer’ is coded from the index entry:
2122 Engineer, aviation (professional)
Where there is only a single index entry that links to a professional unit group, that can used, so for example, the job title ‘Senior quality engineer’ is coded from the index entry:
2461 Engineer, quality
The job title ‘Senior engineer in public health’ is coded from the index entries:
Engineer, senior – see Engineer (professional)
which leads to
2121 Engineer (professional, public health)
In cases of doubt, the person is regarded as non-professional.
There are a few industries in which the job titles ‘Engineer’ and ‘Electrical engineer’ are used in a specific sense so these industries are listed as industrial qualifying terms in the index entries for:
Engineer, electrical, nos
For example, where the job title ‘Electrical engineer’ is recorded with no other information, except that the person is working on merchant vessel Oil Mariner, it is coded from the index entry:
3513 Engineer, electrical, nos (shipping)
The word ‘journeyman’ is ignored when it is used with another job title.
For example, ‘Bookbinder journeyman’ is coded from:
3.7 Leading hand
Where another job title is stated, code to that job title. For example, ‘Leading hand precision engineer’ is coded from:
5224 Engineer, precision
Where no other job title is stated, refer to the index entries for Leading hand indexed as Hand, leading.Back to table of contents
