The US tends to be a lot more spread out than Europe and the rest of the world. It seems like we’re also more likely to move long distances for jobs and the like.
I’m pretty close to most family, 10 to 40 minute drives for everyone that doesn’t live out of state
We all lived in the same state except one uncle until I left (3-4 hour plane ride away) and then went further (15 hours+ across two flights). Mom and stepfather moved south to be warmer on retiring not far from where that uncle had gone. I still live in Japan and everyone else still lives in the state I grew up.
For me, visiting family is now a more time-consuming and expensive adventure, particularly because the one airport anywhere near mom only has a couple of flights a day.
As for the in-laws in Japan, a few hours away from SiL who lives in Tokyo and about an hour away from her parents by billet train.
