Table 6.1 reveals that despite the decline in growth rates, the number of people being added every decade is steadily increasing. Why?                                                                Table 6.1

Year	Total Population (in millions)	Absolute Increase in the Decade (in millions)	Annual Growth Rate (%)
1951 1961 1971 1981 1991 2001	361.0 439.2 548.2 683.3 846.3 1028.7	42.43 78.15 108.92 135.17 163.09 182.32	1.25 1.96 2.20 2.22 2.14 1.93

 

Answer:

The number of people increasing every decade = Total population at beginning of the decade X Growth rate. Since the total population is growing every decade, even though the growth rate is reducing, it is not able to offset the increased total population, i.e., base population. So, the number of people being added every decade is steadily increasing.
