Chile Rate of Natural Increase

The rate of natural increase (RNI) in Chile, which measures the difference between birth and death rates per 1,000 people, is relatively low compared to many of its South American neighbors. As of recent estimates, Chile’s RNI hovers around 0.5% per year, reflecting its declining birth rate and increasing life expectancy—a pattern typical of more developed countries. In contrast, neighboring countries like Bolivia and Paraguay maintain higher RNIs, often above 1.2%, due to higher fertility rates and younger populations. Meanwhile, Argentina’s RNI is similar to Chile’s, though slightly higher, while Peru’s RNI is also modest but still outpaces Chile’s. These differences highlight Chile’s demographic transition towards slower population growth, aligning it more closely with global trends seen in developed nations, whereas some of its neighbors continue to experience more robust natural population increases.
