US Mobility

In a ncie article, the mobility myth, it is pointed out that only 2.7% of Americans cange states each year. My experience is different than that but that is likely because I am in Academia. Still, I am definitely aware of the risks that changing states brings (as you can never know if a state will work out or not in advance).

On the research side, however, this fact is good news for database research as the "lost to migration" rate is low enough to make it unlikely that we will get serious bias in state level medical claims data. That is really useful to know when evaluating MedicAid studies.
