Question

In a population of 1000 at any place, number of individuals born was 150, death in 1 year is 50. Calculate vital index for that year.​

Answer 1

Answer:

Vital Index= $\frac{Natality}{Mortality}*100$

Natality= CBR =$\frac{Live births}{tatal poulation\\} *1000$

                       = (150/1000)*1000

                       =  150 per thousand

Mortality = CDR = $\frac{Live deaths}{Totalpopulation}*1000$

                         =   (50/1000)*1000

                         = 50 per thousand

Vital Index= (150/50)*100

                 = 300

If I am wrong please comment.
