As the time for the 1970 census drew near, Public Advocates founder Bob Gnaizda predicted a vast undercount with resultant shortfall in support for largely minority communities that were being treated as essentially non-existent.  With Gnaizda’s support, the Mexican American Population Commission of California (MAPCC) ​was formed with Gnaizda as its general counsel. Following correspondence between MAPCC and the Census Bureau and a lawsuit, Confederación de la Raza Unida, et al v. George Hay Brown​, the Census Bureau saw the writing on the wall, settled, and adjusted its methods and count of “Spanish Americans.” This revised the count of Latinos upward by 1.5 million people.
