Birth rate is defined as...

• A. (Births / Area) x 100
• B. (Births / Population) x 100
• C. (Deaths / Population) x 100
• D. (Immigration / Population) x 100

Answer: (B)

Birth rate measures how often births occur relative to the size of the population in a given time period. It is the number of births divided by the total population, often converted to a percentage or per 1,000 people. In the given formulas, using births divided by population and multiplying by 100 expresses what fraction of the population is born in that period, which is the birth rate. The other options mix in area (births per area), or use the wrong numerator (deaths or immigration), which would describe other rates, not the birth rate.
