What is birth rate?

Answer and explanation

Correct answer: Number of births per thousand population

Direct answer: A. Birth rate is the number of live births per thousand people during a specified period, commonly one year. In a basic school formula, crude birth rate = live births during the year divided by the mid-year population, multiplied by 1,000. The per-thousand basis allows comparison between places with different population sizes. B is death rate because it counts deaths per thousand population. C is population density, which measures people in relation to land area, usually per square kilometre. D is not a demographic rate at all and does not measure births. A total number of babies alone is not enough for a rate unless it is related to the population and time period. Memory cue: birth rate counts births; death rate counts deaths; density counts people per area.
