Anguilla Rate of Natural Increase

Anguilla’s rate of natural increase (RNI)—the difference between its crude birth rate and crude death rate, expressed as a percentage—is relatively low compared to many of its Caribbean neighbors. As of recent estimates, Anguilla’s RNI hovers around 0.7% per year, reflecting modest population growth driven by a low birth rate and a similarly low death rate. In contrast, neighboring islands such as Saint Kitts and Nevis and Saint Martin exhibit slightly higher RNIs, often exceeding 1%, due to marginally higher fertility rates. However, all these islands share the broader regional trend of declining natural increase, influenced by factors such as emigration, aging populations, and improved healthcare reducing mortality. While Anguilla’s RNI is positive, indicating natural population growth, it is among the lowest in the Eastern Caribbean, highlighting demographic challenges such as youth outmigration and an increasingly mature population structure.
