The RNIE 3 highway of Benin passes through the town of Bassila and the commune. The main ethnic groups in the town are in the order of significance: Yoruba/Nagot who are the native dwellers , as well as smaller migrant communities of Anii and Tem people otherwise known as 'Kotokoli'. The Nagots historically migrated from Nigeria during a westward Yoruba expansion. Given that Bassila is located in proximity to the border with Togo, a significant proportion of the population are of Togolese origin (Anii and Kotokoli migrants). Bassila is the second largest arrondissement in Benin by land area.
