Understanding Risk

How is the risk index calculated?

 

Past Exposure Index

Exposure index values range from 0 to 2. A value of 0 means there are no relevant exposure factors affecting the site. A value of 1 means there have been exposures to crime in the surrounding area within ½ mile, but not at the site; 2 means that exposures to crime exist at the site and the surrounding area within ½ mile.

Future Vulnerability Index

Vulnerability index values range from 1 to 4. A value of 1 represents minimal or no substantial risk; 2 represents more than minimal but below average risk; 3 represents above average risk; 4 represents exceptionally high risk.
