How We Research & Present Data

Data Sources

AutoInsight Pro uses multiple data sources to compile the information presented on this site:

Primary Sources

• National Association of Insurance Commissioners (NAIC): State-by-state premium data, market share reports, and industry statistics
• State Departments of Insurance: Official requirements, regulations, and consumer information from each state's insurance regulator
• State DMV Agencies: Driver licensing, SR-22 requirements, and vehicle registration rules
• Federal Government: NHTSA safety data, FTC guidelines, NHTSA recall databases

Secondary Sources

• Aggregated quote data from industry reports (J.D. Power, Consumer Reports, etc.)
• Academic and industry research on insurance pricing factors
• News reports on legislative and regulatory changes
• Insurer-published rate filings and annual reports

Cost Estimates

When we present premium estimates:

• They are based on aggregated national or state-level data when available
• We use multipliers based on documented factor impacts (e.g., age multipliers from actuarial studies)
• Ranges (±20%) account for individual variation and uncertainty
• All estimates are prominently labeled as such and never presented as quotes or guarantees
• Calculator outputs include explicit disclaimers about their limitations

Updates & Maintenance

This methodology is reviewed annually and updated as needed. Major updates trigger content reviews across affected articles. Last review date: January 2025.
