Question

Find the age standard death rate (S.D.R.) for the following data:

Age  (in years)	Population	No. of deaths
0 - 20	40000	350
20 - 65	65000	650
65 and above	15000	x

Using the above information find x, if the CDR = 13.4 per thousand.

Answer 1

Given CDR = 13.4
ΣDi = 350 + 650 + x

ΣDi = x + 1000

ΣPi = 40000 + 65000 + 15000

ΣPi = 1,20,000

CDR = `(ΣDi)/(ΣP_i )xx 1000`

13.4 = `(1000 + x)/(1,20,000) xx 1000`

13.4 x 120 = 1000 + x

1608 = 1000 + x

x = 608
