Concept & formula
Crude birth rate is defined as the number of live birth per 1000 people in a population.
Numerically, 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.
Calculation
Here, b = number of live birth per year = 1130
and p = mid year population = 49,250
So, CBR = (1130 / 49,250 ) × 1000
= 22.944
= 22.95 live births per 1000 people in a year
So, the crude birth rate for Pinehill County during 2014 is 22.95
