The chart illustrates population trends for four countries: Argentina, Indonesia, Italy, and the Republic of Korea, with data from 2003 and forecasts for 2025 and 2050.
In 2003, Argentina had the smallest population among the four countries, with 34 million people. However, it is projected to experience a significant increase over the next decades, reaching around 81 million by 2050. Similarly, Indonesia, which had the highest population in 2003, is expected to see a substantial rise, with projections indicating a growth from 209 million in 2003 to approximately 323 million by 2050.
In contrast, Italy’s population is forecasted to decline steadily. Starting at 58 million in 2003, it is expected to decrease to around 51 million by 2050. This trend reflects a gradual population decrease throughout the period.
The Republic of Korea shows a relatively moderate change in its population. With a population of 48 million in 2003, it is projected to rise slightly to 52 million by 2025, and remain stable at this figure through to 2050.
Overall, while Argentina and Indonesia are expected to see considerable population growth, Italy is facing a decline, and the Republic of Korea is projected to experience only a modest increase with stability in the long term.
