police and commissioner (sýslumaður) districts have followed the eight region model with the exception that Vestmannaeyjar
form a special district and are not part of the South region. The divisions of Iceland for the purposes of health care and district courts diverge more from the commonly used eight region model.
The postal code system also roughly corresponds with the regions with the first digit of the three digit codes usually being the same as on the map below.
Until 1957, the parliamentary constituencies used in Iceland had been based on its counties and market towns. The reform of constituency borders in 1957 would group these counties and towns together into eight larger areas that form the basis for the modern regional division of Iceland. The differences between the 1957 boundaries and the modern ones are:
The southwestern part of the country was previously divided into Reykjavík on one hand and Reykjanes on the other which encompassed all other municipalities in the vicinity of Reykjavík and on the
Southern Peninsula
on the other
The municipality of Hornafjörður decided in 2008 to leave the association for municipalities in the Eastern region and join the Southern region.[4]Statistics Iceland updated its definition of the statistical regions to reflect this on 1 December 2020.[5]
The area of the former town of Siglufjörður was transferred from the Northwestern region to the Northeastern region when the town merged across the regional boundary with Ólafsfjörður to form Fjallabyggð in 2006.
The area of the former municipality of Skeggjastaðahreppur was transferred from the Eastern region to the Northeastern region when the municipality merged across the regional boundary with Þórshafnarhreppur to form Langanesbyggð in 2006.
The area of the former municipality of Bæjarhreppur was transferred from the Westfjords region to the Northwestern region when the municipality merged across the regional boundary with Húnaþing vestra under the name of the latter in 2012.
