From the following data, find the crude death rates (C.D.R.) for Town I and Town II, and comment on the results :
| Age Group (in years) | Town I | Town II | ||
| Population | No. of deaths | Population | No. of deaths | |
| 0-10 | 1500 | 45 | 6000 | 150 |
| 10-25 | 5000 | 30 | 6000 | 40 |
| 25 - 45 | 3000 | 15 | 5000 | 20 |
| 45 & above | 500 | 22 | 3000 | 54 |
उत्तर
For Town I,
ΣD = 112 and ΣP = 10,000
∴ `"CDR"_"I" = (Σ"D")/(Σ"P") xx 1000`
= `112/(10,000) xx 1000`
= 11.2 per thousand
For Town II,
ΣD = 264 and ΣP = 20,000
∴ `"CDR"_("II") = (Σ"D")/(Σ"P") xx 1000`
= `264/(20,000) xx 1000`
= 13.2 per thousand
As `"CDR"_("I") < "CDR"_("II")`
⇒ Town I is more healthier than Town II.
