Angecourt is located some 8 km south-east of Sedan and 7 km north-west of Mouzon. Access to the commune is by road D6 from Remilly-Aillicourt in the north-east which passes through the commune and the village and continues to Haraucourt in the south-west. About half of the commune in the south and east is forested with the rest farmland.
The Ennemane flows through the commune from south-west to north-east to join the Coupure de Remilly at Remilly-Aillicourt.
In 2009 the commune had 352 inhabitants. The evolution of the number of inhabitants is known through 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" which allow, 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.
