Question

If the Crude Death Rate (CDR) for the following data is 13.4 per thousand, find x:

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

Answer 1

Age groups (in years)	Population	Number of deaths
0 - 20	40,000	350
20 - 65	65,000	650
65 and above	15,000	x
Total	ΣP = 1,20,000	ΣD = x + 1000

CDR = 13.4

`therefore (Σ"D")/(Σ"P") xx 1000` = 13.4

`(x + 1000)/120000 xx 1000` = 13.4

x + 1000 = 13.4 x 120

x + 1000 = 1608

`therefore` x = 608
