Usually don't make random threads for Twitter maps, but this was too interesting to not share:

Some interesting patterns:
-You get an expected borders effect for VA, SC and to a certain extent GA. I wonder if the relative strength of this effect in different areas might be related to the location of the nearest hospital.
-New York seems to be the most common in-migration in parts of NC not on state borders, which makes sense as a large east coast state which has been losing people for a while. You can tell that NE NC or the parts of the Piedmont further away from Charlotte don't get many new people because they have Virginia rather than NYC, even far from the border.
-The Floridian influence on Western North Carolina is very obvious if you've lived in that part of the country but might surprise people from elsewhere. Conversely, TN has a much weaker border effect than you'd expect, due to the Floridians. Florida/New York vs. other states is a pretty good measure of "tourist penetration" in most counties, though Avery is a bit of a converse to that rule.
-Military bases look like America, which is plurality Californian.
-South Carolina is very well represented in Black neighborhoods of several Piedmont cities -- sign of them being more attractive destinations for Black people from SC perhaps? It's interesting though that this would obtain for Winston-Salem and High Point but not Greensboro or the Triangle (though that's less surprising).
-On the flip side, several rich old money white urban areas are more Virginian (and South Carolinian). I assume this is in large part due to these wealthier areas having less new/affordable housing stock. A lot of these places are more "old money southern" than newer built suburbs which look similar in SES but are culturally way less southern and traditionally minded.
-You can see the traces of secondary migration of immigrant communities in several rural areas. Several heavily Latino areas have Texas, Florida, or California, while in Hickory area the influence of the Hmong community gives California in a few precincts. I think the Florida in Sampson and Duplin counties may also be due to the Haitian Community working in nearby Mount Olive, though I'm not sure.
-Two HBCU precincts have Maryland, which makes sense as an answer to the question "Where would people attending an NC HBCU from out of state come from?"
-No clue what's going on in Mitchell, Yancey, or Alexander counties.
