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.
The 2014 numbers make more sense
The census bureau is adding people to all sorts of categories
For example they show whites as 72% in 2015
Then they show whites single race only as 57%
So your comment that Hispanics are a plural majority is also incorrect. They may well become so but they aren’t yet
