That’s funny  

You really think those people are moving because of the weather.

You maybe right, weather or not they have a good life style.

Winter weather, amongst other reasons such as population density.

Explain why some real winter type states like Idaho, Montana and Utah have made some of the biggest population gains?  Not exactly like living on the beach.

"Idaho, Montana and Utah" offer other desirable features- some people like the mountains, less populated areas and the recreation they offer.

Why is Hawaii one of the big population loser's?

Perhaps cost of living in tropical vacation location?

"People move for personal/family and economic/employment reasons. Those who choose to move consider themselves better off by moving. For the economy, migration is one way the labor market adjusts to business cycles and external shocks. For example, absent migration, the labor market’s response to a sharp economic recession is a (steeper than otherwise) rise in unemployment and probably a fall in labor force participation. Migration absorbs some of the shock, which is good for those who stayed. In the long run, sustained net out-migration reduces the state’s human capital and retards economic growth."

And isolation- the longest Interstate Highway in in Hawaii is 27 miles long and none of it- NONE of it leaves the state. 

The people in Oregon are going to have the same damn weather, they just mwant out of a blue state.

And? Whats your point?
