French Guianan voters were asked whether they wanted more power to be given to the local government based in Cayenne.[3] French Guiana was an overseas region and an overseas department of France, regulated by the article 73 of the French Constitution, giving it the same political status as metropolitan departments and regions. The proposed change would have led to it becoming an overseas collectivity, regulated by the article 74 of the French Constitution, similar to French Polynesia.[4]

The referendum was a status change that would have made French Guiana a oversea collectivity instead of a overseas region and department of France, similarly to what French Polynesia currently is. Yet a majority of voters voted against having more power and independence from France.
What reasons have been advanced that could explain why a majority of French Guianan voted against the proposed changes?
