ENUTS3_2013 is the third regular amendment to the annexes to the ENUTS3 classification. ENUTS3_2013 was enforced on 31 December 2013 and was applied from 1 January 2015. ENUTS3_2013 identifies the Nomenclature of Territorial Units for Statistics (NUTS) within Europe in which the household was enumerated. NUTS3 is the third level territorial units within countries. NUTS is a standard administrative division of the European Union and was developed by the EU. The European Free Trade Association extends the NUTS system to several additional countries outside of the EU (e.g. Turkey), and they are also incorporated into this variable.

The first 3-digits of ENUTS3_2013 variable provide the COUNTRY code followed by the 4-digit NUTS3 code. The labels include the standard code for the NUTS3 (2013) system and the name of the NUTS3 region, separated by a slash.

Larger sub-national units are available for most countries in ENUTS1_2013 and ENUTS2_2013.
The full set of geography variables for the countries can be found in the IPUMS International Geography variables list. For cross-national geographic analysis on the first and second major administrative level refer to GEOLEV1, and GEOLEV2. More information on IPUMS-International geography can be found here.

To address issues of changing geography and ENUTS codes, IPUMS has created ENUTS3_2013 as an extension to the ENUTS3 variable. All newer samples post 2010 are available in ENUTS3_2013. Listed below are ENUTS3_2013 and ENUTS3 availability.

Portugal 2011 is not included in ENUTS3_2013 due to changes in boundaries.
