Influence Score
LobbySpend's proprietary 0-100 metric that measures an organization's overall lobbying reach, graded A through F.
Understanding Influence Score
The Influence Score is a composite metric developed by LobbySpend to quantify the relative lobbying influence of organizations that file disclosures under the Lobbying Disclosure Act. The score ranges from 0 to 100 and is converted to a letter grade (A = highest influence, F = lowest). The score is calculated from three weighted factors: total lobbying expenditure (40%), which measures the raw financial resources devoted to lobbying; issue breadth (30%), which measures the number of distinct policy areas an organization lobbies on, reflecting the scope of their policy engagement; and revolving door connections (30%), which measures the percentage of an organization's lobbyists who previously held government positions, indicating access and insider knowledge. Each factor is normalized to a 0-100 scale relative to all organizations in the database.
The weighted sum produces the final score. Organizations that spend heavily across many issues while employing many former government officials receive the highest scores. The grading scale is: A (80-100), B (60-79), C (40-59), D (20-39), F (0-19). Influence Scores are updated quarterly as new LDA filings are processed.
The score is designed to provide a comparable, at-a-glance measure of lobbying activity -- it does not measure the effectiveness of lobbying or imply any wrongdoing. Higher scores reflect greater lobbying activity and presence, not corruption or impropriety.
