Question

Calculate crude death rates (CDR) for district A.

Age group (in years)	Number or persons (in thousands)	Number of deaths
0 - 15	1	20
15 - 60	3	30
60 and above	2	40

Answer 1

ΣD_i = 20 + 30 + 40 = 90

ΣP_i = 1000 + 3000 + 2000 = 6000

CDR for district A = `(ΣD_i)/(ΣP_i) xx 1000`

= `90/6000  xx 1000`

= 15 per thousand.
