This unfairly discounts the immigrants that California attracts , while counting folks who leave. To be consistent we must look at population growth as a whole, possibly split by age group. California will typically attract younger folks looking for work.
It discounts international immigration in from every state, so California isn’t especially penalized in that regard. It’s not unfair—all it does is separate the question of what makes a state a good destination for international immigrants (which involves very specific factors) and the question of what makes a state a desirable place to live for Americans who have unrestricted choices about where to live.
It is true that most American states are unable to attract immigrants. However, they do reap the benefits from the powerhouse states that keep America competitive in the global economic sphere.
