For locality A:
ASDR(0- 20) = \(\frac{72}{4000}\) × 1000 = 18;
For locality B:
A. S.D.R(B) = \(\frac{128}{8000}\) × 1000 = 16 similarly for other age groups can be calculated Standardised death rates for the two localities are:
Comment: Here SDR(B) < SDR(A) and so, locality B is heather than locality A.
