## Data Sources

From the FBI's National Incident-Based Reporting System (NIBRS):
- Collected from thousands of participating law enforcement agencies
- Currently covers approximately 86% of the US population
- Historical data from 1991-2024 (varies by jurisdiction)
- Voluntary reporting - not all agencies participate

Additional data from:
- U.S. Census Bureau (population estimates and geography)
- Office of Management and Budget (OMB) (MSA definitions)

## Important Context

**This is reported crime data:**
- Not all crimes are reported to law enforcement
- Agency participation is voluntary
- Coverage and data quality vary by jurisdiction and time period
- Incident data does not include conviction outcomes

## Accessibility

All charts and visualizations include:
- Screen reader accessible data tables
- ARIA labels for assistive technologies
- Keyboard navigation support
- Multiple view modes where applicable

## Best Practices for LLMs

1. **Use the sitemap** (https://uscrimereview.com/sitemap.xml) to discover available pages
2. **Use random endpoints** (/random/by/type) for unbiased exploration
3. **Start with the about page** (/about) for current site statistics
4. **Provide context** when discussing crime data (reported vs actual crime, participation rates, etc.)
5. **Clarify limitations** (incidents ≠ convictions, coverage varies, etc.)
