The line graph illustrates the changes of urban populations in four countries (Argentina, Brazil, Uruguay, Ecuador) over a period of 50 years ending in 2020, along with predictions for the next two decades. Overall, it is clear that urban populations have grown significantly, albeit at different rates for each country. The forecast predicts a slower rise for the coming two decades.
The two countries with smallest urban populations are Uruguay and Ecuador. In1970, there were only one in fifth populations lived in cities in these two countries. Over the past half century, urban populations in Uruguay has witnessed a significant growth and reached 95% in 2020, while Ecuador indicates a relatively slow rate at 80%.
In Brazil, half of the populations lived in cities in 1970. In 2020 the number rose up to 85%, despite a 8% drop in 2000. Among the four nations, Argentina started with the most urban populations. More than 70% of people lived in cities in 1970. It remained a quite steady growth over the 50-years period and reached more than 90% in 2020. However, Uruguay became the first country with most urban populations surpassing Argentina close to 2020.
Over the next two decades, an overall growth of the urban populations for each country has been predicted. However, only Ecuador shows a greater rise up to 80% in 2040. The other three will see a growth of less than 10%.
