Barges is located some 12 km due south of Dijon. Access to the commune is by the D996 road from Saulon-la-Rue in the north which passes down the eastern side of the commune and continues south-east to Noiron-sous-Gevrey. Access to the village is by the D109 from Épernay-sous-Gevrey in the south which enters the commune in the west and continues north-east through the village and continues east as the D31 to Bretenière. Apart from a significant-sized urban area around the village the commune is entirely farmland.
The Chairon river rises near the village and flows south-east to join the Sans Fond at Beau-Vallon.
In 2010 the commune had 461 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 communes 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 2002Archived 6 March 2016 at the Wayback Machine., 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 and 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 on 1 January 2009 and was based on the census of 2006.
