Northern Mariana Islands Rate of Natural Increase

The rate of natural increase (RNI) in the Northern Mariana Islands is notably low compared to many of its Pacific neighbors. As of recent estimates, the RNI in the Northern Mariana Islands is close to zero or even negative, primarily due to a combination of low birth rates and relatively high emigration rates. In contrast, neighboring countries such as the Federated States of Micronesia and Palau typically exhibit higher RNIs, driven by higher fertility rates and younger populations. For example, the Federated States of Micronesia often records a positive RNI, reflecting a more robust natural population growth. Meanwhile, Guam, another nearby territory, also experiences a low or stagnant RNI, similar to the Northern Mariana Islands, influenced by similar demographic trends such as aging populations and outward migration. This contrast highlights the demographic challenges faced by the Northern Mariana Islands, which, unlike some of its neighbors, is experiencing slow or negative natural population growth.
