The score compares this month's measured safety losses with the five-year norm for the same month. It does not measure every aspect of national safety. What it covers
Read the score on the left, then follow the row across for next month's adjustment to insurance premiums. This month sits in the highlighted row.
Six areas, weighted by how much harm they cause. Each is compared with its own average for the same month over the past five years. Select a row for the numbers.
| Compared with usual | 110% (100% means exactly the usual level; lower is safer) |
|---|---|
| Counts toward NSI | 2.72 of 7.2 points |
The NSS has no explicit road-safety threat; mapped to Health Threats for the injury burden.
| Compared with usual | 95% (100% means exactly the usual level; lower is safer) |

| Counts toward NSI | 1.78 of 7.2 points |
Linked to the mining and low industrial base discussion in NSS 2.3.1.

Floods, droughts and storms, NSS 2.1.2 and 2.3.5.
The score for each month, and the insurance adjustment it set for the month after.
The NSS ranks national threats in four tiers by how likely they are and how much damage they do. Each safety area above is tied to the threat it informs. Threats shown in grey have no safety indicator yet. The score informs 7 of 18 NSS threats, and 3 of 5 in Tier 1.
A national safety and resilience risk index, based initially on measurable, economically consequential events. A single figure cannot describe every threat in the National Security Strategy, so the Authority separates what moves insurance premiums from what it only watches.
Feeds the score and the premium surcharge. Must be a measurable, insurable loss.
Recorded and tracked by the Authority. Never part of the score or the surcharge.
Threats the index does not record, and why.
Methodology v1.0. Read the full method, including which parts are still pilot assumptions.
The surcharge is paid into a separate fund that can only be spent on emergency response and resilience.
It cannot pay recurrent salaries, political spending or general budget gaps.
