Answer:
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.
Explanation:
To determine per capita birth or death rates, you simply divide the absolute number of births ("B") or deaths ("D") by the number in the population ("N") at the midpoint of the time interval (usually year). By convention, for human demographics, we use the total number ("N") of people, regardless of age or sex.
