Question

From the following data. Calculate standardised death rate for locality A and Locality B. Which locality is more healthy?

Answer 1

Since Population B is considered as standard Population computing CDR is same as the SDR for Population B.

SDR (B) = CDR(B) = \(\frac {\textit{No.of deaths occuring in the year}}{\textit{Average population in the year}} \times 1000\)

SDR (B) =\(\frac{∑PB}{∑P},\) B ASDR’s of Population B, P = Standard Population of A.

SDR (A) = \(\frac{38545}{31100}\) = 3939

CDR (B) = \(\frac{410}{31100}\) x 1000 = 13.18

Since SDR of A is less in Locality A, it is more healthy.
