Define age structure, death rate and birth rate.                                      [NCERT]

Answer:

(a) Age structure in the composition of population refers to the number of people in different age groups in a country. The population of a nation is generally grouped in three categories.

India's age structure is:

0-14 years - Children      = 34.4%

15 - 59 years - Adults        = 58.7%

60 and above - Senior citizens = 6.9%

(b) Death rate is the number of deaths per thousand persons in a year.

(c) Birth rate is the number of live births per thousand persons in a year. It is a major component of growth because in India, birth rates have always been higher than death rate.
