Chicago Zoological Society: $94.3M Revenue, $75.5M Expenses

Chicago Zoological Society earns a C on the efficiency rubric — the median bucket on the NonprofitTruth scale, indicating performance close to the national midpoint across financial reserves, officer compensation, and revenue consistency. Composite score: 56/100.

Chicago Zoological Society reported $94.3M in 2024 revenue — a mid-sized nonprofit by U.S. standards. Organizations in this bracket typically operate with a small permanent staff, project-based program structures, and modest reserves. Reserves are the limiting factor: Chicago Zoological Society carries relatively few months of operating expenses on its balance sheet, which can leave an organization exposed if a major funding source pauses.

Revenue has grown meaningfully across the five-year filing history — a sign of expanding donor base, new grants, or scaling programs. Chicago Zoological Society reported $94.3M in 2024, up notably from the start of the window. Compensation for current officers and key employees runs $2.7M against $94.3M in revenue — within the band third-party charity raters typically consider reasonable for an organization of this size and complexity. This is an aggregate across all listed officers, not a single executive's salary. Chicago Zoological Society works in Environment & Animals — environmental, conservation, animal-welfare, and natural-resources programs. The sector spans large international conservation groups and small local land trusts; the financial profile varies accordingly.
