Crude Birth Rate
Definition - What does Crude Birth Rate mean?
The crude birth rate refers to the number of crude births occurring during the year per 1000 population, estimated at midyear. To calculate the rate of population change, the crude death rate is subtracted from the crude birth rate. This calculation does not take migration into account. The birth rate is referred to as crude because it does not take into account age or sex differences amongst the population.
Safeopedia explains Crude Birth Rate
A crude birth rate of more than 30 per 1000 population is considered as high, while a rate of 18 or fewer is considered to be low. The following is an example of how the crude birth rate is calculated:
A country has a population of 1,000,000. 15,000 babies were born last year. By dividing both 15,000 and 1,000,000 by 1000 we arrive at a crude birth rate of 15 per 1000.
