The third term in the calculation, which is essentially an inversefunction of the number of activities conducted by the household,generates a similar result to above. This consequently pushes upthe vulnerability index for WA-MPA households.
Lastly, the fourth term in the calculation of the index is a functionof the position of household incomes compared with the povertythreshold. For this element, where daily cash income is the denom-inator, WA-MPA households logically have a lower average value,which reduces their vulnerability.
