Unlike the East, where families often put down roots that go back centuries, Westerners have always tended to move around. This area breeds an independent spirit, long celebrated in movie and books.

That spirit remains firmly intact, according to recent statistics. Tax return data compiled by the Internal Revenue Service, as reported by Real Estate Insider, shows that more than 10% of Colorado residents relocated from a different county or state between 2013 and 2014 — the highest mobility rate in the country. (Nationally, only 6.4% of returns were filed by those who had changed counties or states.)

Meanwhile, the state has become a magnet for those relocating from elsewhere. Between July 2014 and 2015, the state’s population increased 1.9%, adding 101,000 people, according to Real Estate Insider. This was more than twice the U.S. population growth of 0.8%.

Similarly, the Fort Collins-Loveland and Greeley areas ranked in the top 10 fastest growing cities.

People moving to Colorado most often came from California, followed by Texas, Florida, Illinois and Arizona. Interestingly, those who leave the state move to those areas as well, most often to Texas, followed by California, Florida, Arizona and Washington.
