The bar chart shows the percentage of the total world population in 4 countries in 1950 and 2002, and projections for 2050.

The bar chart depicts the percentage of the total

world

population

in 4 different countries over 100 years starting from 1950.

Overall

, it is evident that the statistics for the earth's

population

decreased for all countries except for

India

. It is

also

noticeable that

India

was the only country where the capacity of the

world

population

is expected to increase by 2050. Looking at the graph in more detail, in 1950 and 2002, China made up the greatest proportion of the

world

population

despite a slight fall in its figures from approximately 23% to 20%. An akin situation could be noticeable in the rate of the

world

populace in Japan and the USA. Their data experienced a decline in the

population

of around 2% over the same period, with figures at around 2,5% and 5% respectively.

In contrast

, the opposite could be seen in

India

, where the figure sharply grew by around 15% from 1950 to 17% in 2002.

On the other hand

, in 2050, the figures for China and Japan are predicted to have a steep fall of around 15% and 2% respectively, whilst the figure for the USA is likely to remain unchanged, at 5%. Meanwhile, the proportion of residents residing in

India

is projected to continue rising to 19%
