Scope of the Arizona Nonprofit Sector

Charitable organizations

Charitable organizations (charities) are IRS-defined 501(c)(3) organizations, of which there are two types: public charities and private foundations.

Public charities receive broad public support in the form of donations and volunteer service, and most of them directly serve people and communities. Ninety-four percent of charitable organizations are public charities. The remaining six percent are private foundations, which typically have revenues derived from a single source of wealth (individual, family or corporation) and support the work of public charities or educational institutions through grants. A minority of private foundations fund and operate their own charitable activities; they are called private operating foundations.

The majority of charitable organizations are based in Maricopa and Pima counties, where Arizona’s major urban centers, Phoenix and Tucson, are located.

While Maricopa and Pima represent the majority of Arizona’s charitable organizations, several counties have as many or more charitable organizations per capita, including Cochise, Coconino, Gila and La Paz counties. The map below depicts the total number of charities based in each Arizona county; the maroon shade reflects density of nonprofits per capita.

Note: Not all nonprofits are required to file a form 990 with the IRS disclosing their financial information. Organizations with over $50,000 in gross receipts were required to file the 990 or 990-EZ, and private foundations were required to file the 990-PF. Religious congregations are not required to file a 990 of any kind.

In 2022, 31% of nonprofit organizations in Arizona reported income to the IRS, totaling $58.2 billion.
