La Bastide-Pradines is located some 50 km south-east of Rodez and 10 km north-east of Saint-Affrique in the heart of the Parc naturel régional des Grands Causses. Access to the commune is by the A75 autoroute which passes through the north of the commune from north-west to east with Exit 46 in the commune and connecting to the D999. The D999 comes from Saint-Rome-de-Cernon in the west and passes through the centre of the commune north of the village and continues east to Exit 47 on the autoroute and to La Cavalerie. The D77 branches from Saint-Rome-de-Cernon by a southern route through the commune and the village and continues east to Lapanouse-de-Cernon. The D560 connects the village to the D999 to the north in the commune. A disused railway line passes through the commune from west to east south of the village. The commune is heavily forested in the south with the rest mainly farmland.
The Cernon river flows through the commune and the village from east to west and continues west then north joining the Tarn east of Comprégnac. The Ruisseau de Coufours rises in the north of the commune and flows south to join the Cernon near the village. The Ruisseau de Saute-Bouc rises in the north-east of the commune and flows south-west to join the Ruisseau de Coufours just north of the village. The Ruisseau des Clarous rises in the south of the commune and flows north to join the Cernon.
In 2010 the commune had 111 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 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.
