Consider the following data:

For which period was the natural growth rate maximum?

1. 1911-1921
2. 1941-1951
3. 1961-1971
4. 1971-1981

• Answer: The correct option is D
• Explanation:

  Natural growth rate = Birth rate - Death rate

  Considering the given years in the options:

  Natural growth rate in the period 1911 -1921 = 48.1 - 35.5 = 12.6

  Natural growth rate in the period 1941 -1951 = 39.9 - 27.4 = 12.5

  Natural growth rate in the period 1961 -1971 = 41.1 - 18.9 = 22.2

  Natural growth rate in the period 1971 -1981 = 37.1 - 14.8 = 22.3

  Hence, for the period 1971 - 1981, natural growth rate was the maximum.
