Nomenclature of territorial units in Polish Statistics (NTS) was prepared based on european Nomenclature of Territorial Units of Statistics (NUTS) - Decree of the Council of Ministers dated 13 July 2000 (Journal of Laws No 58, pos.685) and 2001 year (No 12, pos.101).

NUTS nomenclature is used in collection, harmonization, and data release of statistics of regional countries in EU. It is a basis for development of regional economical accounts, regional agriculture statistics and other domains of regional statistics.

NUTS nomenclature is used for creating regional politics of EU countries and is indispensable for analyses of social and economical development level in regions in terms of regional differences, and for devising regional development programs.

NTS divides Poland into hierarchically connected territorial units on 5 level, of which 3 are characterized as regional levels, and 2 as local ones.

Regional level covers:

  • Level 1 - region area [on 1 May 2004, 6 regions were created; they cover several (2 to 4) voivodships]
  • Level 2 - voivodships,
  • Level 3 - subregions *) (powiats groups).

Local level covers:

  • Level 4 - powiats,
  • Level 5 - gminas.

Levels 2, 4 and 5 are compliant to territorial division of Poland.

The grouping structure in NTS, their symbols and notation, is based on identifiers and territorial division unit names system which is part of TERYT - National Official Register of Territorial Division.
