The bar graph illustrates the proportions of the total world population in India, China, the USA, and Japan in the years: 1950, 2003, and 2050.
Overall, what stands out from the chart is that the population rate in India increased, whereas the rest of the countries experienced the opposite over the time frame.
To begin with, China accounted for the highest inhabitant rate in 1950, comprising approximately 23%. However, in terms of projections, its population rate will plunge and level off at 15%. In contrast to that of China, the number of inhabitants in India will continue to increase until the end of the period and peak at just under 20%, overtaking China.
To elaborate, in 1950 the allocation of the world’s total population in the USA accounted for roughly 7% prior to dropping to 5% in 2003. Regarding future predictions, there will be no oscillation in the figure for it in 2050. Japan — the lowest contributor to the total world population, will witness a significant dip in 2050, representing approximately 2%.
