Periodic reminder that when you see a really cool-looking number you should always ask where it came from and what it means.
Itâs ok. itâs not rude. the number *likes* to be asked personal questions https://twitter.com/chuckleedoright/status/1386089224483524610

My personal favorite question to ask the 72% mover question (because geographer) is how distance is calculated.

Anotherâvery basic, but VERY importantâquestion about the â72% people live within 20 miles of childhood homeâ is simply: where do these data come from??
From usual Census Bureau stats we can calculate folks living in state of birth. Distance is a rarer stat in the US context. https://twitter.com/graykimbrough/status/1386480619652255744

Migration is a bit special (again, I might be biased on this because population geographer), because there are TWO locations to measure: origin & destination. In this case, as @graykimbrough notes, what does âchildhood homeâ even mean? That phrase is doing a lot of heavy lifting.
A quiz!! I *do* like quizzes!!
How far do you live from where you were born?

Good one from @drjosephpierce. I lay in bed thinking about this last nightââmost Americans live close to where they were bornâ must have a lot to do w/age structure? (Itâs ALWAYS age structure)
Places with lots of <18 are going to have lots of people living close to birthplace? https://twitter.com/drjosephpierce/status/1386581684393500672

Also, standard migration disclaimer: folks observed in same place in T & T-1 may still have moved in between. This hidden migration is easy to miss
Am currently ~4,500m from my birthplace, but if I retire in Bloomington, IN & am surveyed there, itâll be like I never moved at all

Iâm always a fan of thinking carefully about the data and you should be too. As my dear friends @minnpop say:
Talk data to me
