Don't forget natural growth, i.e. birth.

According to census estimates, California had a natural population increase of 1,332,394 (births - deaths) from April 2010 -- August 2015. In that same period it had a net immigration of 568,884 people, consisting of +834,999 international and -266,115 domestic.

On the other hand, when you look at the San Francisco bay area metropolitan region, you'll see that there's no domestic exodus and a net immigration of 274,598 people over the last five years.

So, yeah, with a little over ~90,000 new people per year in the region, the picture looks very different than the one the article was trying to paint.
