Peru Rate of Natural Increase

The rate of natural increase (RNI) in Peru, which measures population growth by subtracting the death rate from the birth rate (excluding migration), has been gradually declining in recent years but remains moderate compared to its neighbors. As of the early 2020s, Peru’s RNI is around 1.1% per year, reflecting a steady but slowing population growth due to decreasing fertility rates and improving health outcomes. In comparison, Bolivia and Ecuador generally exhibit slightly higher RNIs, often above 1.3%, owing to higher fertility rates and younger populations. Conversely, Chile and Brazil have lower RNIs, with Chile’s rate dropping below 0.5% and Brazil’s nearing 0.6%, as both countries experience aging populations and birth rates at or near replacement level. Thus, while Peru’s RNI is not the highest in the region, it is still above the South American average, indicating ongoing demographic transition but at a different pace than its neighbors.
