The nation's capital is a glacial fortress, with more than 3,000 Ice People moving in each year while 14,000 Sun People leave in search of sunnier settings. Parenthetically, keep in mind that the index is measuring net migration of Ice People relative to that of Sun People. The iciest places like DC, Alaska, and Maine are all losing people through internal migration, but they're losing Sun People faster than they are losing Ice People (or in the case of DC--the starkest example of white people going in one direction and NAMs going in the other--losing more Sun People than they are gaining Ice People), while top destinations like Idaho show up in the middle of the rankings because people of all races are heading there.
Other states (Alaska, Maine, Montana, South Dakota, and Wyoming) known for being cold prior to the Derb's pessimistic prognostications also tend to be relatively more attractive to Ice People than they are to Sun People. Minnesota, already renowned for its sizable Somali population in Minneapolis, is an exception to this cool rule. Whites and Asians steadily moved out over the period while Hispanics and blacks moved in. North Dakota is another exception, and an apparently anomalous one at that. Pew reports that the state's Hispanic population grew by over 8% annually from internal migration alone, which stands out along with Alaska (where the Hispanic population is reported to have declined 11% per year) as being far higher than Hispanic movement elsewhere.
Steve Sailer has noted that Hispanics tend to vote like whites do, shifted to the left several points. They also tend to move to and from the same places (Hispanics already resident in the US, that is--even though there were hundreds of thousands of immigrants from Latin America pouring into California over the period measured, nearly 300,000 Hispanics already living in the US left California during that time). The correlation between the white and Hispanic rates of change through internal migration at the state level is .45. For whites and blacks, there is no relationship whatsoever, while for whites and Asians it is .21 but falls outside of statistical significance at 90% confidence.
Going through the state data, it becomes clear that blacks don't move across state lines much, while Hispanics are quite mobile. The average absolute rate of change for blacks is 1.1%. It is 1.7% for whites, 5.3% for Hispanics, and 5.8% for Asians (although the high Asian figure is probably an artifact of the way the estimates were made, in increments of 1,000--in states like Montana and Wyoming, a movement of 1,000 Asians nearly doubles or halves the population, depending on which way they're heading). In light of this, it is not surprising that black urban culture emphasizes city of origin as an important marker of identification, manifesting itself in clothing, tattoos, and in the world of hip hop.
* Using US Census data, non-Hispanic whites constitute 65.1% of the US population, Asians 4.6%. 65.1/(65.1+4.6) = .934003, hence the 93% figure (index values are rounded after all calculations have been made). Hispanics comprise 15.8%, blacks 12.9%. 15.8/(15.8+12.9) = .550523, hence the 55% Hispanic figure.
