Northern Mariana Islands is a commonwealth of the United States and is located in the Pacific Ocean. It first became a commonwealth in 1978. Prior to this, the area was part of German New Guinea and the South Pacific Mandate. The region is made up of 14 islands that cover over 183 square miles. Based on the last census taken in the U.S. in 2010, the population of Northern Mariana Islands is 53,883. This puts the population at a low 292.7 people per square mile.

Even though the population is on the rise, the population has not reached its peak. This occurred in 2000, when nearly 70,000 people inhabited the islands. Economic crises and a decline in tourism are just a few of the factors that contributed to the loss of population.
