Question

Calculate the CDR for District A and B and compare them: 

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

(CDR)_A = `(sum "D"_"A")/(sum "P"_"A") = 90/6 = 15` per thosand.

(CDR)_B = `(sum "D"_"B")/(sum "P"_"B") = 145/10 = 14.5` per thosand

∴ (CDR)_B < (CDR)_A

∴ Population of District B is more healthy than A
