This took a little digging, and I'm not surprised there wasn't an answer earlier. My answer uses the available data, but even it is incomplete (you'll see the article below says there is no absolute way to estimate all households that migrate) From the Article: >>An estimated 300,000 "snowbirds" were living in Arizona during the 2002-03 winter season. You're welcome to cook the raw data in any other way you like, but it's not a bad number.My friends in Yuma and Prescott tell me that seems about right as well, 20% more people/traffic/etc.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
