The table indicates the population of four countries in 2003 as well as the predicted information for 2025 and 2050.
Overall, the population figures of three countries are forecast to rise: Argentina, Indonesia and South Korea, but not Italy. Besides, the number of people in Indonesia in 2003 was the highest out of the four, and this country is projected to continue to be the most populous until 2050.
In 2003, Indonesia had the biggest population, reaching 238 million. In contrast, Argentina, which had a population of only 34 million, shows the lowest figure. In the same year, the population of Italy was relatively larger than that of the Republic of Korea, at 54 million and 48 million, respectively.
The projections made for 2025 and 2050 highlight that the population of Indonesia will increase dramatically, with an extra 75 million people in 2050. It is foreseen that Argentina’s population will increase roughly 1.5 times by 2050, whereas that of South Korea is predicted to grow slowly over the course of 22 years from 2003 before levelling out at 52 million. However, Italy’s population in 2050 is expected to be just five-sixths of the initial figure.
