The crude birth rate (CBR) is equal to the number of live births (​b​) in a year divided by the total midyear population (​p​), with the ratio multiplied by 1,000 to arrive at the number of births per 1,000 people. So, there were 14.57 births for every 1,000 people in the city.

How are birth rates calculated?

How do you calculate birth and death rate?

Divide the number of births by the total population and multiply the quotient by 1,000. Death Rate: This metric is calculated the same way as with birth rate, with deaths per 1,000 persons as the numerator.
