The correct definition of “birth rate” is
A) Movement of people across regions and territories
B) No of live births per thousand persons in a year
C) Number of person increased in per 100 of the base population
D) No. of death per thousand persons

Answer 1

Hint: It is the cumulative number of live births per certain number of population divided by the duration of the period in years. The number of live births is usually taken from the universal birth registry system; population counts from the census and projections are made using advanced demographic techniques.

Complete answer:
Number of live births per thousand persons in a year is known as the birth rate. The total number of live births per 1,000 population divided by the duration of the period in years is the crude birth rate in a period. The number of live births is typically taken from a universal birth registration system; population counts from a census and estimation using specialized demographic techniques[clarification needed]. For estimating population growth, the birth rate (along with mortality and migration rates) is used.

Now let us look into the given options
A) Movement of people across regions and territories : movement of people across regions and territories is known as MIGRATION which involves elocation of individuals from one place to another with the goal of permanently or temporarily settling in a new location (geographic region). Thus this is the wrong option (A).
B) No of live births per thousand persons in a year: Number of live births per thousand persons in a year is known as the birth rate. The total number of live births per 1,000 population divided by the duration of the period in years is the crude birth rate in a period.Thus this is the right option (B).
C) Number of people increased in per 100 of the base population : number of people increased in per 100 of the base population is known as world population growth thus this is the wrong option(C).
D) No. of deaths per thousand persons : number of deaths per thousand persons is known as the death rate thus this is the wrong option too(D).

Hence the correct answer is option ‘B’.
