Nonprofits in Illinois: A Data Deep Dive

Illinois — and more specifically, Chicago — is one of the great nonprofit powerhouses of the American Midwest. With 72,340 registered nonprofit organizations generating a combined $182.4 billion in annual revenue and holding $398.7 billion in assets, Illinois ranks sixth among all states in nonprofit economic activity. The state's nonprofit sector is profoundly shaped by three forces: a massive healthcare industry, a deep tradition of organized philanthropy dating to the Gilded Age, and Chicago's role as the economic engine of the Midwest.

Per capita, Illinois nonprofits generate roughly $14,400 in revenue per resident — well above the national average of $12,400 — reflecting the concentration of major hospital systems, universities, and foundations in the Chicago metropolitan area. But the state's nonprofit landscape extends far beyond the Loop: downstate communities rely heavily on local nonprofits for healthcare, social services, and community development in ways that mirror the challenges of rural America.

The Top 10: Healthcare, Education, and Insurance

Illinois's largest nonprofits reveal a sector dominated by healthcare systems and financial services organizations. Here are the state's ten largest nonprofits by annual revenue:

1. Blue Cross Blue Shield of Illinois (Chicago) — $28.4 billion
2. OSF Healthcare System (Peoria) — $8.9 billion
3. Northwestern Memorial Healthcare (Chicago) — $8.2 billion
4. Northwestern University (Evanston) — $7.8 billion
5. Advocate Aurora Health (Downers Grove) — $7.5 billion
6. University of Chicago (Chicago) — $6.9 billion
7. Loyola University Chicago (Chicago) — $3.4 billion
8. Rush University Medical Center (Chicago) — $3.2 billion
9. Chicago Community Trust (Chicago) — $3.0 billion
10. Shirley Ryan AbilityLab (Chicago) — $2.8 billion

The dominance of Blue Cross Blue Shield of Illinois is striking — at $28.4 billion, it alone accounts for roughly 15.6% of all nonprofit revenue in the state. When combined with the major hospital systems, healthcare organizations consume an overwhelming share of Illinois's nonprofit economy.

Chicago: The Nonprofit Capital of the Midwest

Greater Chicago is home to approximately 48,000 of the state's 72,340 nonprofits — nearly two-thirds of all organizations. The concentration is even more dramatic in terms of revenue: Chicago-area nonprofits account for an estimated 80% or more of statewide nonprofit revenue.

This concentration reflects Chicago's historical role as the economic, cultural, and institutional hub of the Midwest. The city's nonprofit infrastructure was largely built during the late 19th and early 20th centuries, when industrial titans like Julius Rosenwald (Sears), John D. MacArthur, and the McCormick family established foundations and institutions that endure today.

The Foundation Ecosystem

Illinois boasts one of the densest concentrations of private and community foundations in the country:

• John D. and Catherine T. MacArthur Foundation — $8.5 billion in assets, famous for its "genius grants" and one of the nation's most influential foundations
• The Chicago Community Trust — One of the oldest and largest community foundations in the U.S., with over $4.7 billion in assets
• Robert R. McCormick Foundation — $1.9 billion in assets, focused on education, communities, and journalism
• Polk Bros. Foundation — Major Chicago funder supporting education, health, and human services
• Crown Family Philanthropies — Significant funder across arts, education, and Jewish communal life

The MacArthur Foundation alone distributes over $300 million annually in grants, much of it flowing to organizations in Chicago and beyond. Its presence has helped make Chicago a magnet for social innovation and policy research.

World-Class Universities

Illinois's higher education nonprofits are significant economic engines:

• Northwestern University (Evanston) — $7.8 billion in revenue, $16.1 billion endowment, home to the Kellogg School of Management and Northwestern Memorial Hospital
• University of Chicago — $6.9 billion in revenue, $11.6 billion endowment, birthplace of the Chicago School of Economics and home to UChicago Medicine
• Loyola University Chicago — $3.4 billion in revenue, the largest Jesuit university in the U.S.
• DePaul University — The largest Catholic university in the nation by enrollment
• Illinois Institute of Technology — STEM-focused institution on Chicago's South Side

Together, Northwestern and UChicago generate nearly $15 billion in annual revenue and hold endowments exceeding $27 billion. Their affiliated hospital systems, research institutes, and community programs extend their nonprofit footprint deep into the Chicago metropolitan area.

Category Breakdown: Where the Money Flows

Illinois's nonprofit revenue distribution by major NTEE category reveals the familiar pattern of healthcare dominance, but with some distinctive features:

• Health (NTEE E): ~$100.3B (55.0%) — Dominated by BCBS Illinois, Northwestern Memorial, Advocate Aurora, Rush, and OSF
• Education (NTEE B): ~$25.4B (13.9%) — Northwestern, UChicago, Loyola, and hundreds of K-12 nonprofits
• Human Services (NTEE P): ~$12.8B (7.0%) — Food banks, shelters, workforce development, social services
• Philanthropy & Grantmaking (NTEE T): ~$10.2B (5.6%) — MacArthur, Chicago Community Trust, corporate foundations
• Religion (NTEE X): ~$5.1B (2.8%) — Over 12,000 religious organizations, reflecting Chicago's diverse faith communities
• Arts, Culture & Humanities (NTEE A): ~$4.9B (2.7%) — Art Institute, Field Museum, Lyric Opera, Steppenwolf, and more
• Community Improvement (NTEE S): ~$3.8B (2.1%) — Neighborhood development, housing, economic development
• All other categories: ~$20.0B (11.0%)

Religious Organizations: A City of Congregations

Illinois has approximately 12,400 registered religious nonprofits, making it one of the top states by count. Chicago's religious landscape reflects wave after wave of immigration: Catholic parishes built by Irish, Polish, Italian, and Mexican communities; Black Baptist and AME churches on the South and West Sides; Jewish synagogues in Rogers Park and Skokie; mosques serving growing Muslim communities; Hindu temples, Buddhist centers, and Orthodox churches.

The Archdiocese of Chicago is one of the largest Catholic dioceses in the country, operating hundreds of parishes, schools, and affiliated social service agencies. Catholic Charities of the Archdiocese of Chicago alone serves over 300,000 people annually through more than 150 programs.

"Chicago's religious institutions aren't just places of worship — they're the backbone of neighborhood identity. In many communities, the parish, the mosque, or the storefront church is the most trusted institution within walking distance." — Chicago Community Trust, 2024 Report

The Human Services Safety Net

Illinois's human services sector is massive, reflecting both the state's urban poverty challenges and its tradition of social service innovation. Key organizations include:

• Feeding America (Chicago) — The nation's largest domestic hunger-relief organization, headquartered in Chicago, coordinating a network of 200 food banks nationwide
• Heartland Alliance — Serves over 500,000 people annually with programs in housing, health, economic security, and justice
• Greater Chicago Food Depository — Distributes 90 million+ pounds of food annually through 700+ partner programs
• Metropolitan Family Services — 165+ years of service to Chicago-area families
• Catholic Charities of the Archdiocese of Chicago — One of the largest private social service networks in the Midwest

Notably, Feeding America — while headquartered in Chicago — operates nationally. Its presence in Illinois reflects the city's broader role as a headquarters city for national nonprofits, including the American Medical Association, American Bar Association, and Rotary International.

Arts and Culture: World-Class Institutions

Chicago's arts scene is one of the richest in the nation, supported by a deep network of nonprofit cultural institutions:

• Art Institute of Chicago — One of the oldest and largest art museums in the U.S., with a collection of over 300,000 works
• Field Museum of Natural History — Home to Sue the T. Rex and one of the world's premier natural history collections
• Museum of Science and Industry — The largest science museum in the Western Hemisphere
• Lyric Opera of Chicago — One of the nation's leading opera companies
• Steppenwolf Theatre Company — Internationally acclaimed theater ensemble
• Chicago Symphony Orchestra — Consistently ranked among the world's finest orchestras
• Shedd Aquarium — One of the most visited aquariums in the U.S.

Together, these institutions generate billions in revenue and serve as major tourist attractions, drawing millions of visitors annually. Chicago's Museum Campus — home to the Field Museum, Shedd Aquarium, and Adler Planetarium — is one of the most concentrated nonprofit cultural destinations in the world.

Downstate Illinois: A Different Nonprofit Landscape

Beyond Chicago, Illinois's nonprofit sector looks dramatically different. Downstate communities — Springfield, Champaign-Urbana, Peoria, Rockford, the Quad Cities — have fewer nonprofits per capita and those organizations tend to be smaller. Key features of the downstate nonprofit landscape include:

• Healthcare as lifeline: Rural hospitals and community health centers are often the largest employers and most critical nonprofits in downstate communities. OSF Healthcare System, based in Peoria, operates 15 hospitals across Illinois and Michigan.
• Agricultural nonprofits: Farm bureaus, 4-H organizations, and agricultural research nonprofits play a more prominent role downstate.
• University towns: The University of Illinois at Urbana-Champaign and Illinois State University in Normal anchor significant nonprofit ecosystems in their communities.
• Community foundations: Local community foundations in downstate cities play an outsized role in funding local nonprofits that national foundations may overlook.

The urban-rural divide in Illinois's nonprofit sector mirrors the state's broader economic and political divisions. Chicago-area nonprofits have access to deeper donor pools, more corporate partnerships, and greater media visibility. Downstate organizations often operate with leaner budgets and more limited infrastructure.

Challenges and Outlook

Illinois's nonprofit sector faces several distinct challenges:

• State fiscal instability: Illinois's well-documented budget crises and pension obligations have historically disrupted funding to nonprofits that depend on state contracts. During the 2015-2017 budget impasse, hundreds of social service nonprofits went months without state payments, forcing some to close.
• Population loss: Illinois has lost population in recent years, particularly downstate, which shrinks donor bases and increases demand for services simultaneously.
• Healthcare consolidation: Mergers and acquisitions among hospital systems continue, concentrating more revenue in fewer organizations and raising questions about community benefit.
• Federal funding uncertainty: With DOGE scrutiny of federal grants intensifying, Illinois nonprofits that depend on federal funding — particularly in health, education, and research — face potential disruptions.

The Bottom Line

Illinois's nonprofit sector is a study in concentration and contrast. The Chicago metropolitan area is home to one of the most robust nonprofit ecosystems in the nation — world-class hospitals, universities, foundations, cultural institutions, and social service agencies that collectively generate over $150 billion in annual revenue. But this wealth coexists with persistent poverty, underfunded rural communities, and a state fiscal environment that creates chronic uncertainty for organizations dependent on government funding. At $182.4 billion in revenue across 72,340 organizations, the Prairie State's nonprofit sector punches above its weight — driven by Chicago's institutional depth, its role as a national nonprofit headquarters city, and a philanthropic tradition that stretches back to the city's founding. The challenge ahead is ensuring that this enormous economic engine serves not just the institutions at the top, but the communities across the state that need it most.
