The rate of natural increase (RNI) in the Philippines, which measures the difference between birth and death rates, remains relatively high compared to many of its Southeast Asian neighbors. As of recent data, the Philippines has an RNI of around 1.5% per year, reflecting a youthful population and higher fertility rates. In contrast, neighboring countries like Thailand and Vietnam have significantly lower RNIs, at approximately 0.2% and 0.7% respectively, due to declining birth rates and aging populations. Indonesia, the region’s largest country, has an RNI of about 1.0%, also lower than the Philippines but higher than Thailand and Vietnam. These differences highlight the Philippines’ ongoing demographic momentum, while many of its neighbors are experiencing slower population growth and, in some cases, approaching population stabilization or decline.
