South Carolina (12,707)
Washington, D.C. (14,064)
Like West Virginia, five of these nine states (plus Washington, D.C.) are in the South. But also grouped here are Alaska and Hawaii, plus two states in the western section of the continental U.S., Idaho and Nevada, that share some geographical similarities with Colorado but aren't as good. Obviously.
North Dakota (20,986)
Even more folks are fleeing the South! Additional New Englanders are splitting! The West is best, but some parts of it are better!
BETWEEN 30,001 AND 40,000 TRANSPLANTS
North Carolina (31,557)
South Dakota (32,739)
The exodus continues in more populous states around the country, plus South Dakota, which has less than one-third the residents (882,235) of the Denver metro area (2,932,415). As such, the 32,739 South Dakotans who now live in Colorado represent nearly 4 percent of their old state's population. Sorry, Pierre and Sioux Falls.
BETWEEN 40,001 AND 50,000 TRANSPLANTS
The most interesting entries here are Utah and Wyoming, a pair of neighboring states with smallish populations — yet more than 40,000 people from each wound up here.
BETWEEN 50,001 AND 100,000 TRANSPLANTS
New Jersey (58,004)
New Mexico (79,706)
The huge numbers of transplants from these thirteen states speak volumes about the wide appeal of Colorado. There are more neighboring states (Nebraska, New Mexico, Oklahoma), where lotsa folks realize that the grass is greener on our side of the fence. Add in Arizonans and Floridians sick of their particular brand of heat and lots of ex-Midwesterners who've had more than enough of the humidity, and the result is an even longer line to get into Colorado.
MORE THAN 100,000 TRANSPLANTS
New York (135,248)
More than 135,000 New Yorkers. Over 155,000 Illinois natives who reached their limit. A whopping 200K from Texas. And so many Californians that if they all lived in one place, it would instantly become the fourth-largest city in the state. If that doesn't put Colorado's incredible growth into perspective, nothing will.
