population of the world in 1950 and 2003, and includes a forecast for the year 2050. Overall, the population of Chinese people during the year 1950 is the largest, as opposed to the lowest figure which can be seen in the prediction for the population of Japan in 2050. Moreover, while all the nations witnessed a gradual decline in their population, the number of Indian people increased rapidly.
During the year 1950, China was worlds most populated country. Far higher than India, USA, and Japan, which accounted for nearly 15%, 7%, and 4% of the total population, respectively. However, an opposite trend was witnessed during the following 52 years, when China lost around 3% of its population. Moreover, a similar pattern was experienced by both USA and Japan, which witnessed a drop of approximately 2%. In contrast, India was the only country which was successful in boosting its population, by increasing from 15% in 1950 to over 17% in 2002.
According to the predictions for the year 2050, while the statistics regarding Japan and China would be decreasing, the population of Americans would stay at relatively the same position as in 2002. On the other hand, India is expected to continue expanding its population until it exceeds that of USA finishing at nearly 19%.
