Quintana Roo, officially Free and Sovereign State of Quintana Roo (Spanish: Estado Libre y Soberano de Quintana Roo), is one of the 31 states which, with the Federal District, comprise the 32 Federal Entities of Mexico. It is divided in 10 municipalities and its capital city is Chetumal.
It is located in Southeastern Mexico, on the eastern part of the Yucatán Peninsula. It is bordered by the states of Yucatán to the northwest and Campeche to the west. To the north, Quintana Roo borders the Gulf of Mexico and to the south, Belize. It also claims territory which gives it a small border with Guatemala in the southwest of the state, although this disputed area is also claimed by Campeche.
Quintana Roo is home of the world famous city of Cancún, the islands of Cozumel and Isla Mujeres, the towns of Bacalar, Playa del Carmen and Akumal, as well as the ancient Maya ruins of Chacchoben, Coba, Kohunlich, Muyil, Tulum, Xel-Há, and Xcaret. The Sian Ka'an Biosphere Reserve is also in the state.
The state officially covers an area of 42,361 square kilometers (16,356 sq mi), but since 1997 there is a boundary dispute with the states of Yucatán and Campeche over an area of approximately 10,200 square kilometers (3,900 sq mi).
The statewide population is expanding at a rapid rate due to the construction of hotels and the demand for workers. Many immigrants come from Yucatán, Campeche, Tabasco, and Veracruz. The state is frequently hit by severe hurricanes due to its exposed location, the most recent and severe being Hurricane Dean in 2007, making landfall with sustained winds of 280 km/h (175 mph), with gusts up to 320 km/h (200 mph).
