• IRS 990 tables are linked by object_id (filing) and ein (organization)
• IPEDS → IRS 990: The ein field in raw_institution links to ein in 990 tables. UD Foundation EINs: 516000297, 516017306
• EADA tables link to IPEDS by unitid; year uses the same fiscal-year convention
• CPI-U is used for inflation adjustment — join on year (and optionally month) to any table with a year column
• Endowment data comes from IPEDS F2 endowment section; 990 total_assets provides a cross-check
• Admin headcount links to IPEDS via institutional context (UD only in first iteration)
