What's up with Wyoming? Video explains why it's 'empty' compared to twin neighbor Colorado

The states are almost identical in size, shape and geographical features, but Wyoming has 580,000 residents to Colorado's 5.8 million.

Wyoming and Colorado have vastly different populations despite being geographically similar.

Most states in the U.S. have oddly shaped boundaries, largely formed by meandering waterways and coastal irregularities. But two states stand out for their seemingly defiant rectangularness—Wyoming and Colorado.

These almost-twin states share a border, are almost exactly the same size (Colorado is just 1.06 times larger than Wyoming), boast basically the same shape and have the Rocky Mountains eating into a sizeable chunk of them. (Wyoming's share of mountains is a bit larger than Colorado's, but its topography isn't nearly different enough than Colorado's to account for how many fewer people it has.)

Wyoming's population as of 2022 was estimated to be just over 580,000, while Colorado's was estimated to be just over 5.8 million. Almost exactly a 10-fold difference between the two very similar states.

So…why?
