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.
If birth rate is more than death rate, it results in positive growth of population.	If death rate is more than birth rate it results in negative growth of population.
