Trinidad and Tobago Rate of Natural Increase

The rate of natural increase (RNI)—the difference between birth rates and death rates—of Trinidad and Tobago is notably low compared to its Caribbean neighbors. As of recent estimates, Trinidad and Tobago’s RNI hovers near zero or is slightly negative, reflecting a combination of low birth rates and relatively stable or slightly rising death rates. This contrasts with countries like Guyana or Suriname, which maintain higher RNIs due to higher fertility rates and younger populations. Similarly, many other Caribbean nations, such as Saint Lucia and Grenada, still exhibit modest positive RNIs, though these too are gradually declining. The low RNI in Trinidad and Tobago is indicative of an aging population and a demographic transition toward slower population growth, while some neighboring countries continue to experience more robust natural population increases.
