Hey it's all stuff from U.S. facturies. Most are here---
---but a lot of them are there too:
LOL
Your info is 8 years out of date, and has no relative term showing the migration of manufacturing to China over the last 35 years?
Beyond absurd
The China map in 1980 would have been empty
It’s meaningless as a comparison
Your map is listing oil and gas production as manufacturing. Sorta disingenuous, don’t you think? Look at some of the places with almost zero infrastructure in Colorado and Wyoming that they are calling major hubs of manufacturing were there is none.
What is it that they are “manufacturing” in Luna County, New Mexico that makes it such a hot spot of industrial activity? What did they do? Just splash paint on a map or turn a chicken loose and see where it crapped to pick their so-called high concentration manufacturing centers? What about Sandoval County? Have you ever been there? Of course not.
