Here's a cool map Seth Kadish posted a couple days ago at Vizual Statistix. It shows the % of workers in counties who commute across state lines. [original post]
I'm especially interested in the area just north of Portland OR, which is Vancouver WA (not Vancouver BC). More than 30% of all the adult workers in Vancouver are heading over that I-5 bridge every day to work! Yikes!
The story is even more interesting on the east coast and in the south... check it out:
Thanks to Seth for sharing this, and again friends, be sure to subscribe to his great blog for many more cool maps and visualizations!!
