I swear I saw a thread recently that claimed that California's population declined for the first time ever. I could be mistaken. A search did turn up this thread:

Probably losing Americans as they get displaced by illegals.
There is one statistic out there that shows California losing something 2 million Middle Class over the past 5 years. Most have gone to Nevada and Arizona.
"California is losing people? That's news to me!"
I can't write that the their is a net loss but there has been a steady migration of people out of CA to state like NV, OR and WA for a long time. Many are, as is cited in the RI article, cashing out of the home to live the life of Riley in other states, even Iowa (Money Magazine). Many are pushed out due to the high cost of housing and CA taxes.
Certainly there is no shortage of illegals entering CA.
They're losing legal Americans, I'm sure that's more than offset by the illegals entering the state.
It's only gaining due to immigration. It's losing a lot of educated native folks.
