The coral of Alghero is among the finest in the Mediterranean with a reputation for quantity, quality, compression and ruby red color. Indeed, this coral is one of the most important economic aspects of the territory, giving this stretch of the coast its name, the [[Riviera del Corallo]]. The coat of arms and flag of Alghero include a branch of the valuable red coral on a foundation of rock.{{Historical populations|1861|8831|1871|9988|1881|9989|1901|10741|1911|11860|1921|12555|1931|13737|1936|15998|1951|21374|1961|26688|1971|32187|1981|36508|1991|39026|2001|38404|2011|40641|2021|42458|type=|footnote=Source: [[Istituto Nazionale di Statistica|ISTAT]]}}
