Access to the commune is by the D206 road from Rustiques in the west which passes through the centre of the commune and the village and continues north-east to Aigues-Vives. The D235 passes through the north of the commune as it goes from Rustiques to join the D135 south-west of Laure-Minervois. The D157 road comes from Marseillette in the south-east through the village and continues north—west to join the D235 in the commune.

The Ruisseau de Trachaman flows from the north of the commune joining the Ruisseau de Buadelle and continuing south-east to the Ruisseau de Réals which flows east out of the commune. The Ruisseau Maire rises in the west and flows east joining the Ruisseau de Canet which flows east through the village to join the Ruisseau Neuf near Aigues-Vives. The Ruisseau de l'Aqueduc forms the southern border of the commune as it flows east to join the Canal du Midi south-west of the commune.
The oldest written mention of Badens is dated November 993 as Villa Badencus in an exchange between Udulgarius, abbot of Caunes, and Roger De Trencavel, Viscount of Carcassonne, concerning Aquaviva which later became Aigues-Vives, a neighbouring village that still exists today.
In 1993 Badens celebrated its 1000 years of existence. On this occasion the village baker baked a cake he called The Millennium. All residents were clothed in medieval costumes and children dressed as knights fought in choreography under the eyes of parents. At the time the commune invited everybody in France called Badens or Ferret to participate in the event and edited a book on the history of the town and with a map of France showing the location of the Badens surnames in France.
In 2010 the commune had 746 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 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.
