That being said, approx. 85% of residents in Bell are latin-americans, so make up your own mind. (No, I don't capitalize American when it is preceded by a hyphen!)
85% is low - the entire area now is more like 92%, (US ancestry = 2.4% according to CityData) and outsiders (”europeans”) are just not welcome. In 2000, the ‘european’ population was about 50%; by 2010 it is less than 7%.
Between 2000 and 2006, “europeans” were routinely victimized(gangharassment/propertycrime/drive-bys) so they moved out of the area as they were able/forced. In 2005, the town voted to go charter city with only 400 votes being cast. By 2009 the ‘city’ was broke, and one of the ‘poorest cities in California’. Town meetings are now held entirely in Spanish....and the Balkanization of California continues....
