Northern Mariana Islands facts on every entity in the world

Under US administration as part of the UN Trust Territory of the Pacific, the people of the Northern Mariana Islands decided in the 1970s not to seek independence but instead to forge closer links with the US. Negotiations for territorial status began in 1972. A covenant to establish a commonwealth in political union with the US was approved in 1975, and came into force on 24 March 1976. A new government and constitution went into effect in 1978.

Economy - overview

The Northern Mariana Islands' economy benefits substantially from financial assistance from the US. In fiscal year 2013, federal grants accounted for 35.4% of the Commonwealth’s total revenues. A small agriculture sector is made up of cattle ranches and small farms producing coconuts, breadfruit, tomatoes, and melons. The Commonwealth’s economy continued to recover in 2013. Real GDP increased 4.4%, following a 2.1% gain in 2012. Economic growth in 2013 reflected increases in consumer spending and exports of services, mainly spending by foreign tourists. Tourism continued to grow in 2013, after posting double-digit growth in 2012. The tourist industry employs approximately a quarter of the work force and accounts for roughly one-fourth of GDP. The Commonwealth is making a concerted effort to broaden its tourism by extending casino gambling from the small Islands of Tinian and Rota to the main Island of Saipan, it’s political and commercial center.
