Chicago Nonprofit Sector Benchmarks 2026

The Chicago metropolitan area is the third-largest nonprofit market in the United States by registered organization count, after the New York metro and Los Angeles County. Approximately 30,000 501(c)(3) public charities are headquartered in the Chicago-Naperville-Elgin metropolitan statistical area, with roughly 23,000 of them registered with the Illinois Attorney General Charitable Trust Bureau under the Illinois Solicitation for Charity Act.

This benchmark report draws on the IRS Business Master File, the NCCS Core File, the Illinois Attorney General’s registration data, the IRS Form 990-PF filings of major Chicago foundations, and AFP Fundraising Effectiveness Project benchmarks to compile the most reliable available picture of the Chicago nonprofit sector’s scale, revenue mix, employment, compliance load, and fundraising performance.

Total Sector Size

Illinois has approximately 73,000 registered 501(c)(3) public charities according to IRS BMF data. The Chicago metro accounts for roughly 30,000 of those — about 41% of the state total. The Illinois Attorney General Charitable Trust Bureau registers approximately 23,000 organizations to solicit in Illinois, a smaller figure because not all 501(c)(3) public charities are required to register to solicit (private foundations, certain religious organizations, and some other categories are exempt from registration).

For comparison: New York City has approximately 40,000 registered public charities; Los Angeles County has approximately 30,000; Houston metro has approximately 15,000; the Washington DC metro has approximately 10,000 (with the highest per-capita density in the country). Chicago’s nonprofit count tracks Los Angeles closely and represents one of the four largest US metro nonprofit markets.

Subsector Composition

The Chicago metro nonprofit sector is heavily weighted toward health care, education, and human services, which together account for the majority of sector revenue. Major subsector revenue concentrations include:

• Hospitals and health systems, dominated by Northwestern Medicine, University of Chicago Medicine, Rush University Medical Center, Advocate Health Care, and Loyola Medicine.
• Higher education, dominated by the University of Chicago, Northwestern University, DePaul University, Loyola University Chicago, and the IIT.
• Human services across housing, food security, workforce development, immigration legal services, child welfare, and behavioral health, with a long tail of mid-sized providers.
• Arts and culture, particularly strong in the metro relative to other US cities of comparable size, with significant concentration in Lincoln Park, the Loop, and Hyde Park.

Operating Budget Distribution

The median Chicago metro nonprofit operating budget is approximately $200,000-$350,000, with a heavy skew toward small organizations and a small number of very large institutions. The mid-sized segment — operating budgets between $500,000 and $10 million — represents roughly 6,000-8,000 organizations. This segment is large enough to require professional development, finance, and program staff, but typically too small to absorb enterprise nonprofit platform pricing.

Revenue Mix

The Chicago metro nonprofit revenue mix is more balanced than NYC’s. Across the sector:

• Government contracts and grants: approximately 40-50% (lower than NYC’s 60%)
• Private foundation grants: approximately 15-20%
• Individual giving: approximately 20-25%
• Earned revenue and program fees: approximately 15-20%
• Other (corporate, in-kind, investment): approximately 5-10%

The lower government share relative to NYC reflects a stronger foundation and individual giving base in Chicago, particularly for arts, education, and policy organizations. The human services subsector remains heavily government-funded, but the cross-sector average is lower than New York’s.

Foundation Concentration

The single most distinctive feature of the Chicago foundation landscape is concentration. A small number of large funders drive a disproportionate share of institutional grant dollars in the metro:

• MacArthur Foundation distributed approximately $290 million in grants in 2023, with a meaningful share going to Chicago-area organizations and policy work.
• Joyce Foundation distributed approximately $50 million in 2023 across its Great Lakes region focus, with strong Chicago concentration.
• McCormick Foundation, Pritzker Traubert Foundation, Crown family foundations, the Chicago Community Trust, Polk Bros. Foundation, and the Lefkofsky Family Foundation add substantial additional grantmaking volume.

The result is that mid-sized Chicago institutions whose grant revenue is concentrated on two or three of these funders carry meaningful concentration risk. A program-area shift at MacArthur (which has happened multiple times in the past two decades) can swing the budgets of dozens of grantees simultaneously. Diversification away from concentrated foundation revenue is a recurring strategic priority for mid-sized Chicago development teams.

Compliance Posture: AG-990 and Audit Thresholds

The Illinois Attorney General Charitable Trust Bureau requires annual AG-990 filings from registered charitable organizations. The financial review attached depends on gross contributions:

• Organizations with gross contributions over $300,000 must attach an independent audit performed in accordance with GAAS.
• Organizations between $150,000 and $300,000 must attach a CPA review.
• Organizations under $150,000 file AG-990 without attached financial review.

Illinois’s audit threshold is materially lower than New York’s $1 million revenue threshold. The practical consequence is that approximately 20-25% of Illinois registered charities cross into mandatory independent audit territory annually — roughly double the NY State share at 11%. For mid-sized Illinois nonprofits, the annual audit is a budget line item earlier in their growth than for their NY peers.

Donor Retention and Fundraising Performance

Chicago nonprofit donor retention tracks national AFP FEP benchmarks closely:

• Sector-wide retention: 43-46%
• First-year donor retention: 19-23%
• Multi-year donor retention: 60-65%
• Recapture rate: 4-8%

What distinguishes Chicago fundraising is the gala and special-events culture, which is unusually deep relative to other US metros. For mid-sized arts organizations, gala revenue can be 15-30% of total revenue. For human services organizations, the major-donor cocktail and benefit dinner is a meaningful acquisition channel.

The labor cost of gala fundraising is substantial. Sector surveys regularly show that net revenue per gala (after staff time, venue, catering, and consultant costs) is meaningfully lower than gross revenue suggests, and the multi-year donor retention rate from gala-acquired donors is below average. Mid-sized Chicago organizations frequently underestimate the all-in cost of their event calendar.

Workforce and Employment

Chicago metro nonprofits collectively employ approximately 350,000-400,000 workers across health care, social services, education, and arts subsectors. Hospitals and health systems account for the largest single employment concentration; human services is second by employment.

Compensation share of revenue tracks the national nonprofit average at 65-75% across the sector, with human services organizations regularly above 75%.

Methodology Notes

This report uses IRS BMF data for organization counts, NCCS Core File data for sector financial figures, IL Attorney General data for registration and AG-990 filing statistics, the relevant 990-PFs for major foundation grantmaking volumes, and AFP FEP for retention benchmarks. Counts and financial figures are most recent available as of late 2025 / early 2026, reflecting FY2023 financial data for the majority of filers.

What This Means Operationally

For a mid-sized Chicago nonprofit with $500K-$10M operating budget:

• The audit threshold ($300K gross contributions) is reached early in the growth path, making annual independent audit infrastructure a near-universal requirement.
• Foundation concentration risk is real and warrants explicit diversification strategy.
• Gala revenue is meaningful but should be evaluated on net basis with full labor cost accounting.
• Government contract administration is required for human services and behavioral health, but the cross-sector average government dependency is lower than NYC, giving Chicago organizations more revenue flexibility.

Operational software for Chicago nonprofits needs to handle audit-ready fund accounting, foundation grant tracking with multi-year forecasting, donor management with strong retention reporting, and event revenue tracking with full cost accounting.

DEFINITION

AG-990

The annual financial filing required by the Illinois Attorney General Charitable Trust Bureau from charitable organizations registered to solicit in Illinois. The AG-990 includes the Form 990 plus state-specific schedules and, depending on revenue, an attached audit or CPA review.

DEFINITION

Illinois Solicitation for Charity Act

The Illinois statute (225 ILCS 460) governing charitable solicitation, registration, and reporting. Most charitable organizations soliciting contributions in Illinois must register and file annually with the Attorney General.

DEFINITION

Concentration risk

A revenue or relationship concentration that exposes the organization to disproportionate downside if a single funder, contract, or major donor reduces or ends support. FASB ASC 275-10-50 requires disclosure of significant concentrations.
