Male priests are referred to as "oungan", alternatively spelled "houngan" or "hungan", while their female counterparts are "manbo", alternatively spelled "mambo". Oungan numerically dominate in rural Haiti, while there is a more equitable balance of priests and priestesses in urban areas. The oungan and manbo are tasked with organising liturgies, preparing initiations, offering consultations with clients using divination, and preparing remedies for the sick. There is no priestly hierarchy, with oungan and manbo being largely self-sufficient. In many cases, the role is hereditary. Historical evidence suggests that the role of the oungan and manbo intensified over the course of the 20th century. As a result, "temple Vodou" is now more common in rural areas of Haiti than it was in historical periods.
