You are incorrect. As of 2014 latinos make up 32% of California’s populace

I am incorrect (may be thinking of LA metro) but it's definitely more then what you say.

As of 2015 it's

Non-hispanic white - 38%

hispanic (any race) - 38.8%

So they are now the plural majority in California.

Up from 4% in 1970.
