Note: Numbers on this page refer to section 501(c)(3) charitable nonprofit organizations other than private foundations, unless expressly stated otherwise. In many cases, these numbers will differ from those in reports prepared by state associations of nonprofits, because they may include tax-exempt organizations other than 501(c)(3) nonprofits, cover a different time period, be based on data retrieved from different sources or at different times, or for other reasons specific to that state. For more information on our terminology and data, see Words, Numbers, Sources.
