What does birth rate tell us?

Answer and explanation

Correct answer: The rate related to births during a period

Direct answer: Option A. Birth rate is a demographic measure that tells us how many live births occur in a population during a specified period, usually one year. It is commonly expressed as the number of live births per 1,000 people in a year. In a basic form, birth rate = live births during the year ÷ population, multiplied by 1,000. The exact denominator may be the mid-year population in formal statistics. Option B is wrong because road length measures transport infrastructure. Option C is wrong because river depth is a physical measurement of water bodies. Option D is wrong because a state boundary describes administrative territory. None of these measures tells us about births. Also remember the difference between birth rate and birth number: a rate compares births with population and time, while a number is only a count. Memory cue: birth rate means births in relation to people and time.
