Question

Calculate CDR for districts A and B and compare them. Also state which district is more healthy..

Age group ( in years )	District A		District B
	No. of persons ('000)	No of Deaths	No. of persons ('000)	No. of Deaths
0 - 15	1	20	2	50
15 - 60	3	30	7	70
60 and above	2	40	1	25

Answer 1

Age group ( in years )	District A		District B
	No. of persons ('000)	No of Deaths	No. of persons ('000)	No. of Deaths
0 - 15	1	20	2	50
15 - 60	3	30	7	70
60 and above	2	40	1	25
Total	6	90	10	145

( CDR )_A = `( ∑D_A )/( ∑P_A ) xx 1000`

              = `90/6000 xx 1000`

              = 15 per thousand

( CDR )_B = `( ∑D_B )/( ∑P_B ) xx 1000`

              = `145/10000 xx 1000`

              = 14.5 per thousand

As ( CDR )_A > ( CDR )_B 
∴ district B is more healthy.
