About
When evaluating a neighborhood for a home purchase or business investment, raw police blotter numbers are insufficient. A count of 500 incidents in a small town is a crisis; in a metropolis, it is a statistical anomaly. This Actuarial Risk Engine standardizes data into the Criminological Standard of Incidents per 100,000 Residents and, more importantly, calculates your Time-Weighted Exposure.
Unlike basic calculators, this tool applies probability theory to determine the likelihood of victimization over a specific tenure (e.g., a 30-year mortgage). It also assigns a Safety Grade (A-F) and estimates the Financial Drag - the hidden cost of crime on insurance premiums and property appreciation.
Formulas
1. Standardization (Rate per 100k):
We normalize the raw count C against population P.
2. Cumulative Victimization Probability (Poisson Model):
To estimate the risk over t years, assuming crime events follow a Poisson distribution with rate λ (where λ = C/P):
3. Financial Drag Estimate:
We estimate the depreciation of asset value D based on the deviation from the national baseline B.
Reference Data
| Safety Grade | Total Crime Rate (per 100k) | Victimization Probability (5-Yr) | Interpretation |
|---|---|---|---|
| A+ (Sanctuary) | 0 to 1,000 | < 4.8% | Exceptional safety. Rare incidents. |
| A (Very Low) | 1,001 to 2,000 | 4.9% to 9.5% | Well below national averages. |
| B (Average) | 2,001 to 3,500 | 9.6% to 16% | Typical suburban/urban mix. |
| C (Elevated) | 3,501 to 5,500 | 17% to 24% | Caution advised. Security systems recommended. |
| D (High) | 5,501 to 8,000 | 25% to 33% | Significant risk exposure. |
| F (Critical) | > 8,000 | > 33% | Statistical certainty of incident over long term. |
