Northern Mariana Islands
The Northern Mariana Islands, officially the Commonwealth of the Northern Mariana Islands (CNMI; Sankattan Siha Na Islas Mariånas; Refaluwasch or Carolinian: Commonwealth Téél Falúw kka Efáng llól Marianas), is an insular area and commonwealth of the United States consisting of 14 islands in the northwestern Pacific Ocean. The CNMI includes the 14 northernmost islands in the Mariana Archipelago except the southernmost island of the chain, Guam, which is a separate U.S. territory. The CNMI and Guam are the westernmost point (in terms of jurisdiction) and territory of the United States.
The United States Department of the Interior cites a landmass of 183.5 sqmi. According to the 2010 United States Census, 53,883 people were living in the CNMI at that time. The vast majority of the population resides on Saipan, Tinian, and Rota. The other islands of the Northern Marianas are sparsely inhabited; the most notable among these is Pågan, which for various reasons over the centuries has experienced major population flux, but formerly had residents numbering in the thousands.
