Estimates of the National Human Security Index Table 10.2: Rank Correlation Coefficients Index of Freedom from ‘Fear’ Index of Freedom from ‘Want’ Index of Freedom from‘Fear’ -0.179 Index of Freedom from‘Want’ Index of Freedom from‘Inequality’ Index of ‘Governance’ Index of Freedom from ‘Inequality’ 0.178 Index of Governance Overall Human Security Index 0.482 0.607 -0.250 0.607 0.571 -0.179 0.071 0.929 The strongest correlation with the overall HSI is of the index of Governance followed by the indices of freedom from‘fear and‘want.’ The near-zero correlation of HSI of the index of ‘inequality’ indicates that inequality has played a different role in influencing the HSI than the other three indices. It is not surprising that there is a moderately strong correlation between the index of governance with the indices of‘fear’ and‘want.’ Chart 10.2: Contribution of the Change in Component Indices to the Change in the Overall Human Security Index As shown in Chart 10.2, the decline in the Human Security Index after 2015-16 is due to over two-thirds of the fall in the index of freedom from‘fear.’ The indices of freedom from ‘inequality’ and governance have also made significant contributions of over 23% and 12%, respectively. It is only the Index of freedom from‘want’ which has made a small contribution to restricting the decline in the overall HSI. 87
