Impact Score Distribution
Distribution of Impact Transparency Scores across all analyzed charities. Higher scores indicate more complete operational reporting, not necessarily greater impact.
Sector Impact Comparison
Average Impact Transparency Score by sector, for sectors with 5 or more charities. Higher scores indicate that charities in that sector tend to report more complete operational data.
Impact Transparency Score -- Methodology
Inspired by GiveWell's cost-effectiveness framework, our Impact Transparency Score measures how completely a charity reports the data needed to assess its operational efficiency. It does not measure actual outcomes or impact -- only the availability of the data required to evaluate them.
Reports program-specific expenses (not just total expenses)
Reports the number of paid staff, enabling cost-per-FTE analysis
Reports volunteer count or volunteer hours, enabling economic value imputation
Reports grants and donations paid out, enabling grant multiplier analysis
More than 70% of expenses directed to programs (GiveWell benchmark)
No data quality or governance red flags identified in CharityData rating
