National Classifications


Country / Area: Ireland

Classification category: Occupation classifications

General information
1 (a)Name of the current national classification (full name in official national languages and in English with acronyms in brackets, should be given)As above the data is translated/concorded to ISCO for transmitting to Eurostat.
1 (b)In which language(s) is the classification available?UKSOC or variations of it are used by a larger number of sections in the office. This is due to the belief that the UKSOC classification reflects the Irish labour market more efficiently than ISCO. For example some of the Irish civil service grades cannot be coded adequately using ISCO.
1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL.-
The structure is similar to that of ISCO, however sections use different levels when coding. The National Employment Survey who collects data using ISCO 88 (COM) use level two. The surveys who use the UKSOC 1990 use level three of the classification.

No additional levels have been added.

Classification structure
2 (a)Please describe the structure of the classification: How many levels does the classification have? (Please provide labels, such as “Division”, “Class”) How many categories exist at each level?This varies across sections, however the majority of classifications used have the same number of categories at the most detailed level as ISCO 88 (COM)
2 (b)Please provide examples of the coding system used at each level.Yes, conversion table are used to transmit the data to Eurostat
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.Central Statistics Office
3 (b)Is the classification structure identical to the international standard or, if not, how does it differ? (e.g. have additional levels been added to the international standard or have changes been made within the level of the international structure, such as aggregations or additional breakdowns)Tara Galvin

3 (c)Please describe deviations from the international standard (in terms of structure, methodology or application rules). Please use examples, if a general statement is not possible.Contact address:

3 (d)At what level of the international standard can data be reported for international comparison? (Please provide examples of programmes / indicators if reporting takes place at different levels of the classification.)The international standard is used by only one section in the office. They began using ISCO 88 (COM) last year for coding, however it is a new survey and has not yet published to date.

The other sections continue to use UKSOC 1990 or variations of it and have no immediate plans to implement ISCO 88(COM) as they believe the UKSOC is a more user friendly classification with efficient coding tools.

3 (e)If no links to international classifications exist or no international standard is used, please state if there are plans to use international norms in the future.The office is currently standardising classifications, therefore all sections will use the one occupation classification in the future. However UKSOC 2000 is the classification being considered as it is deemed to better reflect the Irish labour market.
Classification uses
4 (a)Please state for which statistical purposes (surveys etc.) this classification is used and if there are users outside of the Statistical Office. Please indicate at which level the classification is used for data collection and for data publishing.Household surveys such as the Household Budget survey and the Quarterly National Household Survey. The Census of Population and the National Employment Survey.
4 (b)Please give the names of institutions that use the classification for non-statistical purposes (as opposed to statistical purposes in question 4(a)). Also indicate the kind of use (e.g. tax offices, social security, customs, enterprise register, employment services, work permits etc.)ISCO 88 (COM) is used by the National Employment Survey. The survey uses level two of the classification.
4 (c)Please indicate if alternative classifications are used by other institutions of the economy. Are these classifications available and useful for the Statistical Office?The National Employment Survey is a new survey and has not yet published data to date. They currently use level two of the classification for coding, however as they have not yet published data we cannot answer for definite which level they will publish at.
Implementation / revision status
5 (a)Please state the date of the official adoption of the classification. If not yet adopted, please indicate the current state (e.g. in development, sent for approval, in printing, ready to be distributed etc.)English
5 (b)Please state the date of use of the classification for individual statistical programmes.Yes
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)The UKSOC is accompanied with a very comprehensive manual and coding tools.
5 (e)Please describe the link of the former classification to international classificationsSome Irish occupations are difficult to code using the ISCO 88 (COM) e.g. some civil servant grades.
5 (f)Please describe the structure of the former classification and indicate the number of items at each level of the classification. (similar to question 2(a))Coding tools to assist automatic coding would be beneficial.
5 (g)Do conversion tables exist between the former and current classification?-
5 (h)When was the former classification implemented?-
5 (i)Are statistical data still collected or published according to the former classification? Please indicate if this statistical data is collected or published by the Statistical Office or elsewhere.-
Supporting documents
6 (a)Have national explanatory notes and/or guidelines been elaborated?-
6 (b)Do correspondence tables exist between the national and the international classifications (if applicable)?-
6 (c)Are correspondence tables between alternative and current classification available (if applicable)?-
6 (d)Does a national coding index exist?This varies amongst the classifications used in the office. Of the sections who use UKSOC 1990 they only use level three.
6 (e)Is the classification available in electronic form? If yes, in which formats is it available?(e.g. PDF, TXT, Excel, XML)Yes
6 (f)Are the correspondence tables or indexes available in electronic form?-
