CBR = Bi/P x lOOO
Here, CBR = crude birth rate,
Bi = Number of live births in a year,
P = the estimated midyear population of that year.
It is calculated using the following
formula:
CDR= D/P x lOOO
Here, CDR = crude death rate,
D = Number of deaths in a year,
P = the estimated midyear population of that year.
