Composite Index of Vulnerability to Human Life (M) has also been estimated by taking individual<br />

vulnerability indexes into consideration for both direct (M') <strong>and</strong> indirect (M'') mortality <strong>and</strong> morbidity<br />

[Refer Table 5-5 <strong>and</strong> Figure 5-5].<br />

The functional form specified for aggregation is similar to the one used for estimating Composite<br />

Index of Vulnerability for Housing Stock [Refer Section 5.2.].<br />
