Nonprofit Sector Statistics and Data: Size, Scope, and Economic Impact in the US

The United States nonprofit sector is one of the largest in the world by any measure — organizational count, employment, or share of gross domestic product. This page compiles key statistics on the sector's size, workforce, revenue streams, and economic contributions, drawing on federal agency data and established research institutions. Understanding these figures matters for policymakers, funders, researchers, and organizational leaders assessing the sector's structural role in the national economy.

Definition and scope

The nonprofit sector in the United States encompasses approximately 1.8 million registered tax-exempt organizations, according to the IRS Statistics of Income Division. That figure spans public charities, private foundations, social welfare organizations under 501(c)(4), trade associations under 501(c)(6), religious congregations, and dozens of other Internal Revenue Code classifications. The broadest category — organizations holding 501(c)(3) status — numbered roughly 1.5 million as of the most recent IRS reporting cycle (IRS Tax Exempt Organization Search data).

Not all of these 1.8 million entities are operationally active or required to file annual returns. Religious organizations are exempt from Form 990 filing requirements, and organizations with annual gross receipts below $50,000 file only a Form 990-N (e-Postcard). This creates a structural data gap: the actual number of active nonprofits is likely higher than what federal registration counts reflect.

The National Center for Charitable Statistics (NCCS) at the Urban Institute has historically served as the primary academic aggregator of IRS nonprofit data, disaggregating registrations by organization type, revenue band, geography, and subsector. The NCCS data architecture distinguishes between public charities (the largest and most visible subsector), private foundations (grantmaking entities funded primarily by a single source or family), and other 501(c) types. For a structural comparison of public charities versus private foundations, see private foundation vs. public charity.

How it works

The economic footprint of the nonprofit sector is measured across three primary dimensions: total revenue, total expenditures, and workforce size.

Revenue and expenditures: Public charities alone reported total revenues exceeding $2.6 trillion and total expenditures exceeding $2.5 trillion in a single filing year, according to Urban Institute NCCS analysis. Health organizations — hospitals, health systems, and outpatient clinics — account for the largest share of that revenue, reflecting the dominant presence of nonprofit hospital networks in the healthcare economy.

GDP contribution: The Bureau of Economic Analysis (BEA) estimates nonprofit institutions serving households contributed approximately 5.7 percent of U.S. GDP (Bureau of Economic Analysis, Nonprofit Research). This figure covers the value-added output of nonprofit service delivery but excludes the economic spillover effects of nonprofit employment and procurement activity.

Workforce: The nonprofit sector employs approximately 12.3 million paid workers, representing roughly 10 percent of the private-sector workforce (Bureau of Labor Statistics, Quarterly Census of Employment and Wages). This makes nonprofits the third-largest employment sector in the United States, behind retail trade and manufacturing. Workforce concentration is heaviest in healthcare, education, and social services subsectors.

Revenue composition for public charities follows a consistent pattern when analyzed by organization size:

1. Program service revenue — fees charged for services delivered (e.g., tuition, patient fees, ticket sales) — constitutes the largest single revenue source across the sector, typically representing more than 50 percent of aggregate public charity revenue.
2. Government grants and contracts — federal, state, and local government funding flows to nonprofits through grants, Medicaid reimbursements, and service contracts, representing a substantial secondary revenue stream.
3. Private contributions — individual donor giving, foundation grants, and corporate philanthropy. Giving USA's annual report (Giving USA Foundation) tracks total charitable giving, which exceeded $499 billion in 2022.
4. Investment income — endowment distributions, interest, and dividends, most concentrated among large universities, hospital systems, and private foundations.

Common scenarios

The sector's statistics diverge sharply by organization size, creating two effectively separate operating environments:

Large organizations (revenue above $10 million): This group constitutes fewer than 5 percent of registered public charities but accounts for the majority of total sector revenue and employment. Major hospital systems, research universities, and national human services organizations fall into this band. These entities operate with professional finance staff, formal nonprofit audit requirements, and multi-source revenue portfolios.

Small organizations (revenue below $500,000): The majority of registered public charities operate at or below this threshold. These organizations are typically volunteer-led or employ fewer than 5 paid staff, rely heavily on individual donor contributions and small government grants, and are concentrated in community service, arts, faith-based programming, and local advocacy. Financial fragility is a structural characteristic: a significant proportion of small nonprofits carry fewer than three months of operating reserves, a benchmark identified in research by the Nonprofit Finance Fund.

The geographic distribution of nonprofits follows population density broadly, with California, New York, and Texas hosting the largest absolute counts of registered organizations. However, per-capita nonprofit density — organizations per 100,000 residents — is often higher in smaller states with strong civic and religious traditions.

Decision boundaries

Several statistical thresholds define operational and regulatory category boundaries within the sector:

• $50,000 gross receipts threshold: Organizations below this level file Form 990-N rather than the full Form 990. Failure to file for three consecutive years triggers automatic revocation of tax-exempt status under IRS rules. See nonprofit automatic revocation of tax-exempt status.
• $200,000 gross receipts or $500,000 total assets: The threshold at which a public charity must file the full Form 990 rather than the abbreviated Form 990-EZ (IRS Form 990 instructions).
• $750,000 in federal expenditures: Nonprofits that spend this amount or more in federal awards in a single fiscal year are subject to a Single Audit requirement under the Office of Management and Budget Uniform Guidance (2 CFR Part 200).
• 40 states plus the District of Columbia require charitable solicitation registration before an organization may solicit donations from residents of that state (National Association of State Charity Officials, NASCO).

Understanding where an organization falls relative to these thresholds determines which compliance frameworks apply, which financial reports are required, and which oversight bodies have jurisdiction.
