This population growth was responsible for rapid increase in population from 361 million in 1951 to 683.3 million in 1981. However, since 1981, the rate of growth declined to 2.14 in 1991 and 1.93 in 2001. But the population increased to 846.4 million in 1991 and 1028.7 million in 2001.Despite the decline in growth rate, the number of people being added every decade has increased because India has a very large population. And when a low annual rate is applied to a very large population, it results in a large absolute increase. Thus, in India too the total
    number being added every decade is steadily increasing.

    The enclosures were seen as necessary in England due to the following reasons:
    (i) Rise in the price of wool: In the 16th century, the price of wool increased. The rich farmers wanted to improve their sheep breeds. So they wanted to control large areas of land in compact blocks to allow improved breeding. This led to dividing and enclosing common land and building hedges around their holdings.
    (ii) Population increase and need for more grains: The English population increased from 7 million in 1750 to 21 million in 1850 and 30 million in 1900. This meant an increased demand for food grains to feed the population.
    (iii) Industrialisation : Due to industrialisation, more and more people began to live and work in urban areas. As the urban population grew, the market for food grains expanded, and when demand increased rapidly, food grain prices rose.
    (iv) War between France and England : By the end of the eighteenth century, France
    was at war with England. This disrupted the trade and the import of food grains from Europe. Prices of food grains in England rose significantly.
