Birth rate, frequency of live births in a given population, conventionally calculated as the annual number of live births per 1,000 inhabitants.
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.
