Just for fun, I tried to roughly adjust the top immigrant cities for distance and MSA population. I applied proportions of population over the inverse square of distance, and arbitrarily indexed KC as "1.00". The main takeaway is that Seattle is a massive outlier; for example it's a third the population and over twice the distance compared to Washington DC, but only half the immigration (I'd expect 1/12th, in a vacuum). I think the difference between KC and Springfield/Columbia is also kind of interesting.
MSA Inv. Square Index
Chicago 0.42
Kansas City 1.00
Springfield, MO 1.66
Columbia, MO 1.41
Dallas 0.87
Washington, DC 0.83
Atlanta 0.47
Milwaukee 0.58
Jefferson City 0.78
Seattle 8.03
Somebody else can repeat the exercise for the other direction, I'm too lazy.
Edit: Also, the Chicago migration is less impressive by this index than the article headline implies.
