The most recent record of the population of Argentina is 45,028,946 as of Monday, April 29, 2019. This is based on the latest United Nations estimates. Thus Argentina is not a densely populated country. There is still opportunity for the population growth.
The Argentine population is only equivalent to 0.58% of the total world population. Thus they make up a very small percentage of the world population. They also have a fairly young population with the median age at 31 years. This is an amazingly young nation, and that can be a great factor for the nation if they handle things properly
