      1. BASE DATA: State-level IRS Data Book statistics for Texas
      2. ALLOCATION FACTORS:
         - County population as percentage of state population
         - Median household income relative to state median
         - Industry composition and self-employment rates
         - Historical county recorder lien filing data
      
      3. VALIDATION: Estimates are cross-referenced against:
         - Texas Comptroller economic indicators
         - County recorder public filings (where accessible)
         - TaxCase Review internal case distribution
      
      4. CONFIDENCE INTERVALS: All estimates carry ±15% confidence interval
