Hazard and exposure overlays
The occupied-home count represents exposure. Hazard and vulnerability categories are ordinal labels; multiplying them does not produce a probability of loss. A screening rule is supplied for this fictional exercise.

Fictional hazard and exposure layers. Original fictional resource; not an official map or real dataset.
Resource description
A: High hazard, 180 occupied homes, vulnerability index 1; B: Medium hazard, 70 occupied homes, vulnerability index 1; C: High hazard, 90 occupied homes, vulnerability index 2; D: Low hazard, 180 occupied homes, vulnerability index 3. The vulnerability index is ordinal, not a probability.
Use the resource carefully
State the unit and the part of the resource you used. A pattern in a fictional dataset is evidence for that exercise; it does not establish a fact about a real place.
Check whether an explanation is supported by the data or needs additional geographical knowledge. For statistical tasks, a calculated result does not establish causation or significance by itself.
