Arbellara is located some 6 km east of Propriano and 2 km south of Fozzano. Access to the commune is by road D19 from Viggianello in the west which passes through the village then continues north to Fozzano. The D119 road goes south from the village then turns south-west to join the D69 which goes north-east then north to Loreto-di-Tallano. Apart from the village there is also the hamlet of Acoravo in the south-east of the commune at the intersection of the D119 and D69. The commune is mostly mountainous and forested.
The southern border of the commune is formed by the Rizzanese river which flows west to the Mediterranean Sea south of Propriano.
In 2009 the commune had 134 inhabitants. The evolution of the number of inhabitants is known from the population censuses conducted in the commune since 1793. From the 21st century, a census of communes with fewer than 10,000 inhabitants is held every five years, unlike larger towns that have a sample survey every year.[Note 1]
^At the beginning of the 21st century, the methods of identification have been modified by Law No. 2002-276 of 27 February 2002, the so-called "law of local democracy" and in particular Title V "census operations" allows, after a transitional period running from 2004 to 2008, the annual publication of the legal population of the different French administrative districts. For communes with a population greater than 10,000 inhabitants, a sample survey is conducted annually, the entire territory of these communes is taken into account at the end of the period of five years. The first "legal population" after 1999 under this new law came into force in 1 January 2009 and was based on the census of 2006.
