Not long ago, I heard someone jab, "We should change our state motto. It should be, 'If you seek a pleasant peninsula, move to Florida.'"
So, being the data-minded person that I am, I decided to run the numbers to see whether that's been the case. The Census Bureau is nice enough to give estimates for how population changes for each state on a year-to-year basis. Basically, you can have 'natural' changes due to births and deaths and you can have migration. Census even adds extra fun to it by estimating increases due to international immigrants and internal migrants. Are people moving out of Michigan? Are people moving into Florida?
I plugged the numbers into the chart below. (Unfortunately, our graphics person was out right now, so you get the dull-looking Excel version)

So, while less people are moving into Florida, more people are leaving Michigan. Doesn't necessarily mean that Florida is more pleasant, but more people are seeking opportunity and improvement there.
