This piece is part of the Slate 90, a series that examines the multibillion-dollar nonprofit sector. Read all stories from the Slate 90 here, and view the Slate 90 nonprofit rankings here. You won’t find the YMCA on the Slate 90, partly because while the brand is national, the corporate structure is more fragmented. There is an umbrella national council of American YMCAs that had revenues of $144 million in 2015, but that’s a separate organization from, say, the YMCA of Greater New York ($188 million), the YMCA of San Diego ($156 million), or the YMCA of Greater Houston ($128 million).
