Although Argentina’s population numbered by approximately 70% initially, holding the highest amount of dwellers, the nation’s growth over several decades was gradual, and thus it was exceeded by another country.
When the year 2020 arrived, the difference of amount of city dwellers in all the countries mentioned had decreased, as three nations’ percentage converged just below 100%, with Ecuador being the exception, ranging by over 60%. For 2030 to 2040, Argentina’s, Brazil’s, and Uruguay’s percentage is expected to remain stable. Meanwhile, Ecuador is expected to increase even further.
