Saint Barthelemy Rate of Natural Increase

Saint Barthelemy, a small French overseas collectivity in the Caribbean, experiences a relatively low rate of natural increase (RNI) in its population growth. The RNI, which is the difference between the crude birth rate and crude death rate, is close to zero or even slightly negative in Saint Barthelemy due to its low birth rates and an aging population. In contrast, many of its neighboring Caribbean countries, such as Saint Martin and Saint Kitts and Nevis, tend to have higher RNIs, driven by higher birth rates and younger populations. However, like much of the Caribbean, these neighboring islands are also seeing a gradual decline in RNI as fertility rates fall and populations age. Unlike some larger Caribbean nations, Saint Barthelemy’s population growth is more influenced by migration than by natural increase, making its demographic trends distinct from its neighbors, where natural increase still plays a more significant role in population growth.
