By 2007, Idaho had 4.6 percent more white people than it had in 2005, making it the country's #2 Whitopia for that period. During those years 384,000 residents of America (i.e., not immigrants from foreign countries) moved into Idaho and 307,000 moved out. So, net, Idaho added 77,000 Americans from interstate migration over that period, of whom 53,000 were white.
The term "whitopia" comes from a black author, Rich Benjamin, whose recent book Searching For Whitopia: An Improbable Journey To The Heart of White America, took him to places like Coeur d'Alene, Idaho, which he found to be pretty darn nice. In the course of his research, he took up golf and discovered that he really enjoys it. (The fourth picture down here is of the Coeur d'Alene golf course.)
Interestingly, Hispanics only accounted for 2,000 and Asians 1,000 of the net increase in Idaho. Blacks, however, made up 22,000 of the net increase in Idaho. So, Idaho is also a new Blacktopia. Who knew?
In 2008, McCain carried 65 percent of the white vote in Idaho.
In contrast, the #1 Whitopia for 2005-2007 is a place where Obama carried 86 percent of the white:, of course, Washington D.C. The nation's capital lost from interstate migration (i.e., not from immigration/emigration), net, 37,000 blacks, 5,000 Hispanics, and 2,000 Asians. But it gained 10,000 whites, for a net increase in its white population of 5.1 percent just from 2005 to 2007.
According to the 2008 exit poll, whites accounted for 35% of all votes in D.C., despite a huge black turnout for Obama. African-Americans were down to 56%. This sense within D.C. of the inevitable triumph of white liberal technocrats, leading to a whitopia of good public schools and high property values, was given a rude shock by the technocratic Fenty administration being given the boot in 2010 by black voters.
