National Classifications

Nomenclature d’Activités Tunisienne
(NAT 2009)

Country / Area: Tunisia

Classification category: Activity 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)Nomenclature d’Activités Tunisienne (NAT).
Tunisian Industry Classification (NAT).
The current version is NAT 2009.
1 (b)In which language(s) is the classification available?Headings and Explanatory notes in French and Arabic.
1 (c)Can the classification (or information about it) be accessed on the Internet? If yes, please provide the URL.Yes,
URL : http://www.ins.nat.tn/publication/nat_2009.pdf
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?NAT consists of a hierarchical structure. The structure of NAT 2009 is described in as follows:
Level 1: 21 sections identified by alphabetical letters A to U;
Level 2: 88 divisions identified by two-digit numerical codes (01 to 99);
Level 3: 274 groups identified by three-digit numerical codes (01.1 to 99.0);
Level 4: 662 classes identified by four-digit numerical codes (01.11 to 99.00).
2 (b)Please provide examples of the coding system used at each level.For example, the activity “Manufacture of communication equipment” is identified by the code 26.30, where 26 is the code for the division, 26.3 is the code for the group and 26.30 is the code of the class; section C, to which this class belongs, does not appear in the code itself.
Relationship to international standards
3 (a)Is this classification based on (or linked to) an international standard classification? If yes, please describe.Yes;
NAT 2009 is derived from NACE Rev.2, itself derived from ISIC Rev.4.
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)NAT 2009 is derived from NACE Rev.2. The first level and the second level of NACE Rev.2 (sections and divisions) are identical to sections and divisions of NAT 2009. The third and fourth levels (groups and classes) of NACE Rev.2 are subdivided in NAT 2009 according to National requirements. However, groups and classes of NAT 2009 can always be aggregated into the groups and classes of NACE Rev.2 from which they were derived.
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.There are no deviations from the international standard.
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.)Data can be reported for international comparison at 4 digits (classes).
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. 
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.NAT is used for all statistics regarding economic activities : all business survey principally the annual business survey, Labor Force Survey,...
NAT is used for coding the main activity of each enterprise in the National Business Register
NAT is used for data collection (usually collected either at the 4 digit level), data publishing, synthesis (ex: National accounts)
Data is published at some specific aggregated levels according to the user requirement and availability of information.
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.)Other institutions (e.g general tax office, Social Security Office) generally use alternatives classifications to administrative requirements (tax offices, social security).
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?Alternative classifications are still used by other institutions for administrative purposes (e.g tax offices, social security). Correspondence tables have been developed between these alternative classifications and official classification (NAT) especially for the management of business register.
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.)The Tunisian Industry Classification (NAT 2009) was adopted in 2009 as an official standard. NAT 2009 replaces the former (previous) Tunisian Industry Classification of the year 1996 (NAT 1996).
5 (b)Please state the date of use of the classification for individual statistical programmes.2010
5 (c)Are there existing plans for revision or update of the current classification?Update in relationship with update of CITI and NACE
5 (d)Name of former (previous) national classification (full name in both national tongue and in English with acronyms in brackets, should be given)NAT 1996.
5 (e)Please describe the link of the former classification to international classificationsNAT 1996 is compatible with NACE Rev.1 at the 4 first level, national "level 5" (subclass) consisting of one digit takes account of national requirements.
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))The structure of NAT 1996 is described in as follows:
Level 1: 17 sections identified by alphabetical letters A to U;
Level 2: 60 divisions identified by two-digit numerical codes (01 to 99);
Level 3: 221 groups identified by three-digit numerical codes (01.1 to 99.0);
Level 4: 501 classes identified by four-digit numerical codes (01.11 to 99.00)
Level 5: 595 subclasses identified by five digit numerical codes (01.11.1 to 99.00.0).
5 (g)Do conversion tables exist between the former and current classification?Yes

5 (i)Are statistical data still collected or published according to the former classification?
