For contrast, review the population pyramids for India by selecting the years 1970 and 2015. Compare these pyramids to those of China for the same years. What difference can you see?

Answer

The shape of the population pyramids for India and China in 1970 is almost identical. Both look a lot like a true pyramid, with about 29% of the population under age 10 and a steady drop-off from age 25 or older. However, India in 2015 is quite different from China in 2015. The top of the graph is a sharply pointed pyramid, with a modest cylinder shape only at the bottom. And the age-group under 10 still makes up 19% of the population, showing considerable potential for rapid growth in the coming decades.

The form of India's and China's population pyramids in 1970 is nearly identical. Both resemble a true pyramid, with nearly 29 percent of the population under the age of 10 and a gradual drop-off after the age of 25. However, India in 2015 is not the same as China in 2015. The graph's top is a sharply pointed pyramid, with only a modest cylinder shape at the bottom. Also, the under-10 age group already accounts for 19% of the population, indicating significant prospects for rapid growth in the coming decades.
