The D324 road also comes by an indirect route from La Neuville-à-Maire in the west to the village. The southern quarter of the commune is forested with the rest farmland.
The Ruisseau de Terron with its tributaries rises in the south of the commune and flows north-west forming part of the western border before continuing north-west to join the Bar near Malmy. The Ruisseau de Charlier forms part of the eastern border of the commune before flowing west through the centre to join the Ruisseau de Terron on the western border.
In 2010 the commune had 59 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.
