ENUTS1 identifies the Nomenclature of Territorial Units for Statistics (NUTS) within Europe in which the household was enumerated. NUTS1 is the first 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, and they are also incorporated into this variable.

ENUTS1 corresponds to the 2010 version of NUTS1 released by Eurostat.

The code labels include the standard code for the NUTS1 system and the name of the NUTS1 region, separated by a slash.

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.

Comparability — Index


Comparability — General

All EU samples except Hungary and The Netherlands provide the necessary geographic detail and are included in ENUTS1.

Smaller sub-national units are available for most countries in ENUTS2 and ENUTS3.

Comparability — France [top]

The 2006 and 2011 samples include overseas regions (Guadeloupe, Martinique, Guyane, and Réunion), which are not available in earlier French samples.

Comparability — Germany [top]

The 1970 and 1987 samples are from the West German censuses, while the 1971 and 1981 samples are from the East German censuses. Cases coded to Berlin are from East or West Berlin, depending on the sample.

A number of cases in 1981 have unknown geography within Germany.

Comparability — Poland [top]

ENUTS1 is only available for the 2002 and 2011 Poland samples. In 1998, Poland's previous 49 voivodships were organized into 16 voivodships with drastically different geography. To be concurrent with current NUTS geography, only the 2002 and 2011 Poland samples were included.

Comparability — Romania [top]

The 1977 sample has been harmonized using the integrated geographic variable provided by the Romanian statistical office, which enables the comparability of the 1977 and 2002 samples. However, the counties of Alba and Arad are not included in the 1977 sample. The absence of these counties involves RO1 / Macroregiunea Unu and RO4 / Macroregiunea Patru, respectively.
