Question

Given the following information : 

Age groups
(in years)
Population Number of deaths
0 - 20 40,000 350
20 - 65 65,000 650
65 and above  15,000 x

Find X, if the CDR = 13.4 per thousand. 

Solution

Given                            CDR = 13.4
Total population`(∑P_i)=40000+65000+15000`

                                  =`120000` 

No of Deaths `(ΣD_i)`  = `350+650+x`

                                  =`1000+x` 

             `  CDR=(ΣDi)/(∑ p i)xx1000` 

⇒ `13.4=(1000+x)/120000xx10000` 

⇒ `13.4=1000+x/120` 

⇒ `13.4=(1000+x)/120` 

⇒ x=`1608-1000` 

∴ `x=608`
