It is expressed as the number of live births in a year per thousand of population. Identify the correct option.
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → Crude Birth Rate
Option (1) Total Fertility Rate — Incorrect. It is the average number of children per woman, not live births per thousand of population.
Option (2) Crude Birth Rate — Correct. The crude birth rate (CBR) is the number of live births in a year per thousand of population. Births are one of the three components of population change.
Option (3) Migration — Incorrect. Migration is the movement of people from one place to another, the third component of population change; it is not a count of births.
Option (4) Child-women ratio — Incorrect. It is a ratio of young children to women of child-bearing age, not a count of births.
Note: The concepts in Option (1) and Option (4), ‘Total Fertility Rate’ and ‘Child-women ratio’, are not in NCERT (2025-26); explained here for the benefit of the students.
NCERT (2025-26): “Components of Population Change … There are three components of population change – births, deaths and migration. The crude birth rate (CBR) is expressed as number of live births in a year per thousand of population.…” |
