A referendum on becoming an overseas department of France was held in Mayotte on 29 March 2009. In contrast to the four other similar regions (Guadeloupe, Martinique, Réunion and French Guiana), Mayotte would not have become a DOM/ROM but would only have had a single assembly; the four DOM/ROM will have the option of changing their status to this format, as well.
Mayotte will become the 101st French department and the first with a 95% Muslim population in 2011 as a result of the "yes" vote.
