The critical organisational datum of the occupational information resources collated on the GEODE project is an 'occupational unit group' (OUG) identifier. This is a numerical index of occupational locations, defined according to an externally documented scheme. On this page, we document (partially for our own administrative purposes) all the OUG schemes which have so far been 'curated' within the GEODE resources, and have some occupational information associated with them indexed under the GEODE service.

International Occupational Unit Group schemes

 

ISCO-08	International Standard Classification of Occupations 2008
Description:	ISCO-08 is a standardised occupational unit group scheme, published by the International Labour Office. It was first published in 2008. It is designed to be implemented across countries and is recommended for international comparative research. Applicable from 2008, it was designed as a revision on the 1988 ISCO scheme. Many of its occupatonal unit groups and subgroups are identical to the ISCO-88 categories, but there are also many changes between ISCO-08 and ISCO-88 (a concordance table is published by the ILO).
Structure:	4-digit numerical index, valid values from 0 to 9629. Hierarchical structure incorporating 3-digit, 2-digit and 1-digit subgroups. Subgroups are indexed by truncation, but are also commonly incidated by trailing zeros (e.g. 513 may also be indicated as 5130).

ISCO-68 (unit groups)	International Standard Classification of Occupations 1968 (unit groups) (3-digit)
Description:	ISCO-68 is a standardised occupational unit group scheme, published by the International Labour Office. It is designed for international comparative research, with applicability between 1968 and 1988 (although many data sources published after 1988 still use ISCO-68 codings). It was designed as an update from an earlier version of ISCO developed in 1958, and it is related to the 1988 revision to ISCO. The three digit version of ISCO-68 (unit group) is the most widely employed, but a more detailed 5-digit version (occupational categories) is also available.
Structure:	3-digit numerical index (valid values fall in the range 10-999, but some applications use values greater than 1000 to indicate unclassified occupations). Some publications insert a hyphen between the first and second digits (e.g. 192 becomes 1-92). Sequential (partially hierarchical) structure incorporating 2-digit (minor) and 1-digit (major) subgroups. Other variants of the ISCO-68 scheme are also in common use (see below)

Switzerland

BTAP (1990)	Berufliche Tatigkeit/Activite Proferssionnelle (as used on the census of 1990)
Description:	BTAP is a name used to describe the standardised occupational unit group scheme used by the Swiss statistical offices around the period of the 1990 census.
Structure:	5-digit numerical index (range 10001-47101, athough values in range 51100 to 51106 are sometimes used to classify the non-employed by educational level, whilst 3- and 4-digit versions are used to indicate subgroups). There is a structure of 3 major groups (1-digit), 25 submajor groups (2-digit), and 85 minor groups (3-digit). These are obtained through hierarchical truncation (although the major group classification involves the additional recoding such that truncation units 3, 4 and 5 are merged to 3). Trailing zeros are used to incorporate subgroups as valid unit group locations, such that the subgroup unit is multiplied by 100 to obtain  a 3-5 digit unit group (e.g., occupational unit group 22301 is located within major group 2, submajor group 22 and minor group 223; in the five digit version there are represented through the categories 200, 2200 and 22300 respectively).

SOC-2010	UK Standard Occupational Classification 2010
Description:	SOC-2010 is the standardised occupational unit group scheme used by the UK Office for National Statistics, and in most nationally coordinated UK occupational data collections, for the period 2010-. SOC-2010 represents an adaptation of its precursor scheme, SOC-2000. In many instances, the same codes apply to the same occupations in both schemes. Notable differences between SOC-2010 and SOC-2000 include a difference in the definition of 'managerial' roles with the consequence of a reallocation of many jobs with managerial titles away from major group 1; and the reclassification of a number of female dominated jobs from Major group 3 to Major group 2 (see ONS 2010: 4-7).
Structure:	4-digit numerical index . Hierarchical structure incorporating 4-digit (369 different unit groups); 3-digit (90 'minor groups'); 2-digit (25 'sub-major groups') and 1-digit (9 'major groups') versions. In some datasets, trailing zeros are also used to indicate subgroup membership with a 4-digit code, e.g., occupation 5000 implies major group 5; 5200 implies sub-major group 52 (this is typically done when an occupation is ambiguous and only the higher level group can be ascertained).

Introduction to Occupational Unit Group schemes

The consistent analysis of occupational information hinges upon the definition and documentation of 'occupational unit group' (OUG) schemes. These schemes are categorical definitions of occupational locations and titles, in which each location is usually indexed through a numerical value. Most people have probably seen a few different OUG schemes at some stage; they are usually recognisable as a dictionary format definition of different occupational titles.

Broadly three types of occupational unit groups are identified in the GEODE project, namely classifications/taxonomies of:

• Occupational titles (the most common resource stored at GEODE)
• Employment status categories (typically distinguishing a handful of different status positions, and often analysed in combination with occupational titles)
• Industrial classifications

 

More discussion of the documentation of occupational information resources and the critical role of occupational unit group schemes can be found in several of the GEODE project publciations, in particular the 2007 article 'Data curation standards and social science occupational information resouces' within the International Journal of Digital Curation.

Occupational Unit Group schemes are critical to the analysis of occupational information for two reasons:

• A reliable way to record and preserve accurate details on occupatational locations is to translate it to an appropriate OUG scheme and store the OUG data (in a typical example, the processing of a survey data question on occupational titles would involve coding textual descriptions of occupational activities into numerical OUG values by using a coding software tool such as the UK based CASCOT software).
• The most reliable way to link micro-social data on occupational locations, to aggregate occupational information, is to use an externally defined 'file linkage' or 'translation key' which connects OUG locations with substantively meaningful occupational information. In fact, most of the GEODE project resources are of exactly this nature: information resources which connect OUG positions with relevant aggregate occupational information about those resources, such as data on which social class categorisation a particular OUG should be located in, or, say, the proportion of women to men found in the relevant OUG.

Some useful things to know about occupational unit group schemes are that:

• There are lots and lots of different OUG schemes. Most countries have their own OUG system, which is typically updated every ten years or so. There are also severally cross-nationally comparable OUG schemes.
• Most OUG schemes index a large volume of different occupational locations. Typically most national schemes might index about 300-600 different occupational titles. Specialists in occupational information are often interested in even more differentiated OUG schemes which might list several thousand different occupations.
• Most OUG scheme use numerical indexing systems which have some level of hierarchical or sequential organisation within them. For example:
  • the UK SOC 2000 OUG scheme uses a 4-digit numerical index system which is hierarchically organised: valid values range from 1111 to 9259; all occupational locations begining with 1 (namely, 1111 to 1239) also belong to 'Major Group 1', a group known as 'Managers and Senior Officials'; all occupational locations begining with 9 (namely, 9111 to 9259) belong to 'Major Group 9', a group known as 'Elementary Occupations'; all occuptional locations begining with 22 (namely, 2211 to 2216) belong to 'Submajor group 22'; etc.
  • the US SOC 2000 OUG scheme uses a 3-digit numerical index system which is sequentially organised: valid value range from 1 to 983; all occupations in the range 1-43 belong to 'subgroup 1: Managment occupations; all occupations in the range 470-496 belong to 'subgroup 17: Sales occupations'; etc.
• Some OUG schemes use indexing systems which pose problems to basic computer programmes for data analysis. For instance, some OUG schemes record data in text ('string') classifications rather than numerical indexes. Other OUG schemes are partially hierarchically organised, but subject to some inconsistencies in the operation of that hierarchy.
• There are numerous published resources which connect OUG locations with other social science information. The GEODE project is concerned with improving the provision of the linkage to those resources. Some other internet links to such resources are provided on a section of the GEODE homepage.

 

Thus, the specification of data in terms of OUG schemes is critical to the organisation of the GEODE project resources. Because there are so many different OUG schemes available to social scientists, a key problem involves navigating between different OUG schemes, and recognising when certain data is coded to an appropriate scheme.

The mechanics of the GEODE provision involve using metadata systems to enable connections to be made between micro-social and aggregate occupational information resources. Critically, the metadata for each data resource must state which OUG scheme or schemes the data is relevant to. In order to make that statement, it is helpful in turn to have a resource listing all recognised OUG schemes. This page, which is partially designed for internal usage within the GEODE project, serves that purpose. On this page, we list the series of OUG schemes for which GEODE data resources have hitherto been connected. The listing includes some descriptive data about each scheme, and a unique 'uri' location which identifies, for the purposes of our metadata, the specific name of the OUG. (This page lists all OUG schemes which 'curated' GEODE resources cover. There may be uncurated GEODE resouces within the GEODE portal covering certain OUG schemes which are not yet listed on this page).

 

 

User notes:

• All materials on this page are authored by members of the GEODE research team.
• The records are ordered by the type of OUG (occupational title; employment status; industry) then herien alphabetically by country.
• The most important information, for the purposes of the GEODE project, is the 'GEODE URI' record. Other aspects of each record are filled in optionally. Some have considerable detail, others are much briefer records.
• Many OUG schemes may appear to contribute more than one record. This is usually because we wish to differentiate between alternative OUGs, which arise from the same structural definition, according to the different levels of occupational detail that they refer to. For example, the 'ISCO-88' scheme is recorded at the 4-digit level, but for our purposes, a separate OUG scheme, 'ISCO-88 (1-digit)' defines ISCO data which is only recorded at the single numerical digit of detail.
