Argentina’s rate of natural increase (RNI)—the difference between its crude birth rate and crude death rate—has been gradually declining over recent decades, currently standing at around 0.7% per year. This is lower than the RNI of some of its neighbors, such as Paraguay and Bolivia, which both have RNIs above 1.2%, reflecting higher birth rates and younger populations. In contrast, Argentina’s RNI is similar to that of Brazil (approximately 0.6%) and higher than Uruguay’s, which has one of the lowest RNIs in South America at around 0.3%, due to its aging population and low fertility rates. Thus, while Argentina’s population is still growing naturally, its growth rate is moderate compared to some neighbors and indicative of broader demographic transitions in the Southern Cone.
