Last December, statistics showed that Colorado is the second fastest growing state in the country (behind only North Dakota), thanks to the addition of more than 100,000 new residents between July 2014 and July 2015. And a large percentage of them wound up in the Denver area.
But where did they come from? Sparefoot.com provides some fascinating answers to that question.
Drawing from U.S. Census Bureau data between 2009 and 2013, the site discovered that 64 percent of those who moved to Denver County during that span — 42,674 people — relocated from another county in Colorado.
That means that the remaining 36 percent, representing 23,751 people, came from out of state — and Sparefoot figures show the actual numbers for 29 U.S. counties.
Many of the digits confirm what longtime residents have long suspected, based simply on the license plates seen on local roadways. For example, three California counties are in the top six, including the number-one place when it comes to new Denver residents — more than 4,000 of them. But there are plenty of surprises along the way.
Count down the photo-illustrated top 29 below, featuring each county's ranking and the number of people from there who moved to Denver County circa 2009-2013. Click to check out Sparefoot's original post.
