Samoa Rate of Natural Increase

The rate of natural increase (RNI) in Samoa, which measures the difference between birth rates and death rates, is moderate compared to its Pacific neighbors. As of recent estimates, Samoa’s RNI is around 1.3% per year, reflecting a relatively high birth rate and a declining but still significant death rate. This rate is somewhat lower than that of nearby countries such as Tonga and the Solomon Islands, which have RNIs closer to 1.5%–2%, due to their slightly higher fertility rates and younger populations. In contrast, Fiji’s RNI is similar to or slightly lower than Samoa’s, as Fiji has experienced a greater decline in birth rates and increased emigration. Overall, while Samoa's population is still growing naturally, its RNI is moderate for the region, indicating a gradual demographic transition compared to some of its neighbors who are still experiencing faster natural population growth.
