 <p>Changing administrative regional boundaries over time complicates the construction of consistent regional panel data. The <code>nuts</code> package can transform <strong>European regional data</strong> identified by <strong>NUTS codes</strong> between different <strong>versions</strong> and <strong>subdivision levels</strong> with the aim to harmonize and link data sets.</p>
 <p>The package’s main task is to convert data between all NUTS versions in use: 2006, 2010, 2013, 2016 and 2021. These conversions can be performed in any direction based on <strong>spatial interpolation</strong> using five different weights (regional area in square kilometers, 2011 and 2018 population size, 2012 and 2018 built-up area). The weights are based on conversion tables provided by the <a href="https://urban.jrc.ec.europa.eu/tools/nuts-converter" class="external-link">Joint Research Center (JRC) of the European Commission (EC)</a> that are used in their online converter. The <code>nuts</code> package permits to do the same conversion offline with additional advantages such as the conversion within groups, enabling the conversion of datasets with multiple NUTS versions efficiently.</p>
