Ignoring the age of people in this data seems like a mistake. Considering the age of boomers and the states this article says people are moving to, I would venture a guess that recent retirees make up decent percentage of the people moving. Two 30 year olds moving from California to Nevada so they can afford to raise a family is saying something fundamentally different and in my opinion more important than two 65 year olds moving from New York to retire in Florida.
