You're right. From what i've read, while almost 95% of the population is Catholic, according to some studies, many also practice Vodou alongside Christianity.power i wrote: Can't find it now, but I did read it was vodou. But of that Catholic majority, I'm betting most of them practice it.
So, while the majority are Catholic and the state religion is Catholicsm, Vodou certainly plays a large role in their culture/belief system as well.
