Alaska seems quite developed from the Fairbanks to Anchorage corridor, but you don't have to go far off the highway for it to be complete wilderness. I spent some time there and you'd drive on roads for miles and then they just end - in the sense the road doesn't go any further and everything after that is pretty much wilderness with maybe a few unused logging roads.
We stuck to pretty much the main roads, but I went to Denali as well, so I've experienced how vast and beautiful it is.
I was just curious and looked up the population density. Alaska has a population density of 1.3 people per square mile and Yukon just 0.07 per square km. If I did the math right Yukon has a population density of 0.027 people per square mile. Or Alaska is about 5 times more densely populated.
Of the 34 thousand people that live in all of Yukon, 25 thousand live in Whitehorse. That leaves just 9k people for everywhere else.
